Do you know if the berry can still be activated by Alakazam after Ninjask has obtained it's effect? (sorry if I wasn't supposed to post that here) In other words, can the berry be activated by the tricker, since they do have the berry.
 
It can still be activated by Alakazam if its HP drops below 1/4 (normal activation) but Trick does NOT copy the activation effect. It's just like Tricking an ordinary berry.
 
Does Pursuit against a faster U-Turner still have a chance to hurt itself in its confusion (assuming the Pursuiter is Confused, of course)?
No.


I tested it 3 times and not a single time that the animation and the words about that it's confused came up.


I also took a video of me testing it if you want to make sure I didn't do anything wrong.

My Pursuiter was Starapter with 152 speed holding Iron Ball
U-turner was Smeargle with 110 speed.
 
Okay, I just ran a bunch of tests on the Custap Berry, sparked by whistle's discovery.

First I confirmed his findings. I had my Banette with Trick and my Shuckle start the battle. My Electrode with less than 1/4 max HP and a Custap Berry was also in my team. I was fighting the twins' two Pachirisu on Route 4.

Round 1:
Shuckle switches to Electrode
Pachirisu uses Quick Attack
Pachirisu uses Quick Attack
Banette uses Trick and gains the Custap Berry

Round 2:
Pachirisu uses Quick Attack
Pachirisu uses Quick Attack
Electrode uses its None to move first
Electrode uses Thunder (slays a Pachirisu)
Banette uses Taunt

So that's confirmed. Then I tried the same thing only with Banette holding a Lum Berry instead of nothing. Sure enough, the Electrode used its Lum Berry to move first and the Lum Berry was consumed. Then I tried an Everstone. The Electrode used its Everstone to move first and the Everstone was consumed.

I also did some tests concerning the circumstances under which the Custap Berry (or, theoretically, the substituted item) is actually consumed.

First I entered a Pahcirisu battle with my Banette and my Electrode leading. The Electrode already had below 1/4 HP and a Liechi Berry. The Electrode immediately ate the Liechi Berry, even before I chose moves for the first turn.

I then started the same battle, but with the Electrode holding a Custap Berry.

Round 1:
Banette uses Snatch
Pachirisu uses Quick Attack
Pachirisu uses Quick Attack
Electrode uses Thunder and KOs a Pachirisu

Round 2:
Banette uses Snatch
Pachirisu uses Quick Attack
Electrode's Custap Berry allows it to move first
Electrode uses Thunder and KOs the other Pachirisu

This was not what I expected. I figured the Custap Berry would be eaten on Round 1. I tried a slightly different test.

Round 1:
Pachirisu uses Quick Attack
Pachirisu uses Quick Attack
Electrode's Custap Berry allows it to move first
Electrode uses Thunder and KOs a Pachirisu
Banette uses Taunt on the other Pachirisu

OK, that's more like it. So it looks like Custap Berry didn't activate on Round 1 of the earlier test because the Electrode was the last Pokémon to move. That would be sort of like how Protect and Detect fail if the user is the last Pokémon to move. But why did the item get eaten on the second turn? I then tried another test where the Banette used Snatch every turn and the two Pachirisu used Quick Attack every turn. My Electrode kept using Taunt and didn't ever consume the Berry. But once I killed off one of the Pachirisu, the berry got eaten, even though the Electrode still moved last out of all the surviving Pokémon.

For one final test, I brought in my Electrode with Custap Berry and my Steelix with Roar.

Round 1:
Pachirisu uses Quick Attack
Pachirisu uses Quick Attack
Electrode's Custap Berry allows it to move first
Electrode uses Taunt on a Pachirisu
Steelix uses Roar on a Pachirisu (fails)

In this test, since Quick Attack has a +1 priority and Roar has a –6 priority, the Custap Berry could not have benefitted the Electrode, but it was eaten anyway. It appears that the item gets consumed as long as there is either a Pokémon that hasn't yet moved or an empty slot on the field.

EDIT:

I did another test, where my Steelix had a Custap Berry and my Dusclops whittled down the Steelix's HP with Night Shade. The Steelix used Roar every turn. The turn after the threshold was reached, the Dusclops KOd a Pachirisu and the Steelix didn't eat the Berry. The next turn, the Berry was eaten (right before Roar). So on the turn that a slot is emptied, that slot's 'action' is still taken at its predetermined time (before Roar, in this case). Also, a slot that starts out empty is not considered to have 'taken an action' until at least after all priority –6 moves. My guess is that such a slot is never considered to have taken an action at all.

Conclusion:
The Custap Berry's game mechanic is comprised of three parts:

1. If at any time the holder of a Custap Berry has its HP fall below the 1/4 threshold, that Pokémon's Custap Berry flag is switched from its default value of FALSE to TRUE. (Or, if you're a Shoddy programmer, the Pokémon gains a new Custap Berry status effect).

2. At the beginning of each turn when turn order is calculated, any Pokémon with the Custap Berry flag set to TRUE will be placed in the turn order before other Pokémon using moves of the same priority.

3. When a Pokémon takes an action (other than switching out), if its Custap Berry flag is set to TRUE and there exists on the field at least one slot (Pokémon position) that has not taken an action this turn, the Pokémon consumes whatever item it's holding and its Custap Berry flag is set to FALSE.

Note: Using Pursuit against a fleeing Pokémon is an exception. This will never result in the Pursuit user's flag being set to FALSE or the item being consumed.

Note: If a slot contains a Pokémon that gets KOd, that slot still takes its (empty) action on that turn at the time that the former occupant would have acted. A slot that begins a turn with no occupant does not ever take an action.

Note: If a Pokémon has its Custap Berry flag is set to TRUE and its HP rises above the 1/4 threshold, the flag is not set back to FALSE.

P.S. This was all tested using a North American version of Pokémon Diamond.
 
I'll post some evidence later, but I can confirm that this "Custap glitch" happens in PBR too. It happened to me in a random Wifi battle.
 
Question: It says in the Mold Breaker entry of our AbilityDex that Mold Breaker bypasses the SpDef boost caused by Flower Gift. If my Mold Breaker Pokémon is attacking the partner of my opponent's Flower Gift Pokémon, is the SpDef boost ignored then?
 
Gravity: The issue of how Gravity raises your effective accuracy is still unknown. How I would test it is by using Double Team once under Gravity. If it's actually -2 evasion for all, moves would have 4/3 their normal accuracy, but if it's * 5/3 accuracy, moves would have 3/4 * 5/3 = 5/4 their normal accuracy, meaning a 75% accurate move (Sleep Powder without CompoundEyes) would have 100% accuracy for -2 evasion, but 93.75% accuracy (possibly rounded to 93%) for * 5/3, as I suspect it is. If you ever miss Sleep Powder, it's not a -2 evasion stage change. What is known that it is not a +2 accuracy alteration, meaning it affects evasion or it is * 5/3 accuracy. The only difference between the two (* 5/3 accuracy or * 3/5 evasion) is possible rounding issues, but I don't think there is enough information on how accuracy works to determine that.

I don't know if this has been confirmed or not. I used a Blissey with Gravity / Egg Bomb / Iron Tail (all 75% accuracy), and out of 120 uses of the moves in Gravity against an opponent having used Double Team once, not one missed. I think this shows that Gravity indeed increases a move's accuracy by a factor of 5/3, i.e. all pokemon's evasion falls by 2 stages in Gravity.

I already tested this using Sleep Powder (another 75% acc. move), and it missed after about seven uses, IIRC. My results are on the second page here.
 
Wait, so Sleep Powder missed after seven tries? Are you sure that Gravity hadn't run out when you used the Sleep Powder that missed? Because I just did a test and my 75% accuracy moves didn't miss out of 120 tries....

EDIT: This was done in a European version of Pokemon Diamond.

I'm positive that it hadn't. I paid close attention that Clefairy always selected Gravity if it had run out and was still sleeping, and since Clefairy was the faster of the two, there's no chance that Sleep Powder would have hit during non-Gravity conditions. Keep in mind that I did this in Pearl; if you did the test in Platinum, perhaps that's an indication that they may have changed how Gravity works.
 
Okay, I'm back with a new discovery. You know how every Pokémon move has a bunch of flags that are set to TRUE or FALSE? They are as follows:

1. Does the user make physical contact with the foe? (For Rough Skin, Static, etc.)
2. Is the move blocked by Protect?
3. Can the move be reflected with Magic Coat?
4. Can the move be stolen by Snatch?
5. Do BrightPowder and Lax Incense affect the move's accuracy?
6. Does a King's Rock or Razor Fang give the move a flinch chance?

In Serebii's AttackDex, Flag #5 is listed as 'BrightPowder'. In actuality, this flag has nothing to do with BrightPowder, or even with accuracy checks. It's easy to see that there are several moves that have this flag set to TRUE that are not affected by BrightPowder. All never-miss moves, for instance, have this flag set to TRUE. This, however, is not a proof. So, I gave my Wobbuffet BrightPowder, taught my Dusclops Focus Punch, and went to fight the two Pachirisu. After about 12 tries, the Dusclops missed the Wobbuffet with Focus Punch. Focus Punch has 100 base accuracy and Flag #5 set to FALSE. Hence, Flag #5 does not control whether BrightPowder lowers a move's accuracy.

So what does it do? After carefully examining the move database, I developed a theory which turned out to be correct. If Flag #5 is set to TRUE, the targets of the move remember being hit with it for the purposes of Mirror Move. I tested this with some moves that I had not previously tested with Mirror Move. Spit Up, for instance, seemed to fit the profile for a move that Mirror Move could replicate. Yet its Flag #5 is set to FALSE. Testing revealed that Mirror Move could not replicate it and the Pokémon did not remember being hit with it.

I also tested Mirror Coat (Flag #5 = FALSE) and Metal Burst (Flag #5 = TRUE) in a single battle against a wild Ditto. Sure enough, Metal Burst can be replicated, but Mirror Coat cannot.

The one 'exception' is Trick Room. For some reason, Trick Room has its Flag #5 set to TRUE. However, Trick Room is the kind of global effect that doesn't actually target any Pokémon and therefore no Pokémon on the field remember being targeted by it.

Conclusion: The flag labeled 'BrightPowder' in Serebii's MoveDex has nothing to do with BrightPowder, but actually determines whether the target of the move can remember and replicate it with Mirror Move.

Also: If a Pokémon with Unburden loses a Berry to Pluck, it still gets the Unburden Speed boost.
I used my Drifblim with Spit Up for testing and I decided to test this while I was at it.
 
Has anyone ever tested Trick + Unburden on Drifblim? On Shoddy, Trick activates it even if you gain another item in return. Intuitively, this doesn't seem right.
 
I don't know if this has been confirmed or not. I used a Blissey with Gravity / Egg Bomb / Iron Tail (all 75% accuracy), and out of 120 uses of the moves in Gravity against an opponent having used Double Team once, not one missed.

Yes, this does contradict previous testing, which is concerning. After 120 uses, it has a very small chance to never miss...

I think this shows that Gravity indeed increases a move's accuracy by a factor of 5/3, i.e. all pokemon's evasion falls by 2 stages in Gravity.

Those are two very different things, which is the whole purpose of the test. If it increases accuracy by a factor of 5/3, then it will always increase accuracy to 5/3 of the original, regardless of other state changes. If a move has a final accuracy of 30%, you'll end up with a 50% accurate move under Gravity.

If it makes a stage change to evasion, then there is no constant multiplier. It's only identical to * 5/3 when evasion hasn't been altered. If any evasion stage changes (such as Double Team or Sweet Scent) are in effect, then the two will not give the same result.
 
I can always redo my test to make sure that I didn't indeed screw something up (even though I'm positive I didn't, it WAS a month or two ago when I did the test).

Just to make absolutely sure, I'll be using a slower Oddish with Sleep Powder and a faster Clefairy with Gravity and Double Team. I'll enter into an in-game double battle against the twins south of Floaroma Town.

Turn 1 - Clefairy will use Gravity, Oddish will do whatever to one of the Pachirisu, the two Pachirisu will do whatever.
Turn 2 - Clefairy will use Double Team, Oddish will use Sleep Powder on Clefairy, the two Pachirisu will do whatever.
Turn 3+ - If Gravity runs out before Clefairy wakes up, Clefairy will use Gravity when it wakes up, then Oddish will use Sleep Powder the following turn (I just remembered: my last test I would have Oddish use Sleep Powder the same turn - does Gravity not affect evasion/accuracy the turn it's used?). If Gravity hasn't run out when Clefairy wakes up, it will merely use Cosmic Power while Oddish uses Sleep Powder. Repeat as necessary.

If this is acceptable, I'll perform my test when possible (in the middle of a Pokeradar chain atm) and let everyone know what my new results are.
 
(I just remembered: my last test I would have Oddish use Sleep Powder the same turn - does Gravity not affect evasion/accuracy the turn it's used?).

That is a strong possibility. I'm pretty sure that abilities like Swift Swim don't activate the turn rain is started in a double battle, so it wouldn't surprise me if this modifier doesn't apply until the next turn. If you do use Sleep Powder on the turn Gravity is used during your next test, you should note if it misses on that turn specifically.
 
The accuracy boost from Gravity should take effect immediately. The only reason that Swift Swim doesn't take effect until the following round is that turn order is calculated before any Pokémon take action. The other effects of Rain Dance (more powerful Water-type moves, etc.) are applied immediately.
 
1stly I'm sorry if this is a repost, but I went through most of the oldies and didnt see these.

Has anyone tried to use Skill swap on a pokemon with mold breaker to obtain Wonderguard?? It seems like a bit of a stretch but it might work. Mold breaker normally goes through wonderguard.

^Edit^: I did it myself, actually, and it fails. But you get a 'the move fails' message, instead of the normal 'its blocked by wonderguard message'.

Also in a 1vs1 battle, if a pokemon with Moldbreaker uses heal bell, will it cure the status of soundproof pokemon not in the field?
 
I'm wondering whether using the ability Synchronize in the overworld to attract Pokemon with the same nature requires the Pokemon having the ability (say Abra) healthy and in the lead.

An example scenario would be like this:

I have a Bold Abra with the Synchronize ability in the lead but it is fainted and cannot battle. As a result, Pachirisu, which is in the second slot, battles the Pokemon that I encounter.
Will I be able to battle Pokemon with the Bold Nature 50% of the time?
Or would the ability be rendered useless?

Hmm.. it's not only Synchronize that I am concerned.
What about those other abilities affecting the overworld?
(Flame Body, Compound Eyes, Keen Eye, etc.)

I would really appreciate the help of the research team regarding this matter.
Thank you and please keep up the good work :D
and sorry if this was researched before.

Yes, if you have a fainted Pokemon with an ability like Synchronize or Magnet Pull in the lead, its ability will still affect the appearance of wild Pokemon. However, the ability of the Pokemon in the second slot, even if the Pokemon in the first slot is fainted, won't affect wild Pokemon.
 
Also in a 1vs1 battle, if a pokemon with Moldbreaker uses heal bell, will it cure the status of soundproof pokemon not in the field?

I just tested this and yes, if a Pokémon with Mold Breaker uses Heal Bell, a Pokémon with Soundproof that's not in battle will have its status healed. These were some excellent questions, The 198.

On another note, I've done some testing concerning accuracy and evasion levels and found that they work quite a bit differently than we've been led to believe. I began to become curious when I read this description of the accuracy check logic ostensibly taken from the game code:

• The opponent's evasion stat stage is subtracted from the attacker's accuracy stat stage.
• The Accuracy stat stage is adjusted so it is neither less than -6 nor greater than 6.
...

If this is true, it has two implications. First, a combination of accuracy reduction and evasion boosting totaling to x is equivalent to x levels of accuracy reduction or x levels of evasion boosting (as long as x < 6). To test this, I had my Pidgeot use Double Team 3 times and used Sand-Attack three times on my partner Shuckle. Shuckle then started firing Gastro Acids (a 100% accurate move) at the Pidgeot.

If prevailing wisdom were true, the chance to hit would be 100% * 1/2 (for –3 levels of accuracy) * 1/2 (for 3 levels of evasion) = 25%. If the alternative method of calculating accuracy were true, the chance to hit would be 100% * 1/3 (for –6 total accuracy levels) = 33.3%.

Out of 100 Gastro Acids, 63 hit and 37 missed, bringing us much closer to the new hypothesis.

The second implication is that if x in the above equation is greater than 6, it's treated as 6. I tried the same test, only with 6 Double Teams and 6 Sand-Attacks. If prevailing wisdom were true, the chance to hit would now be 100% * 1/3 * 1/3 = 11.1%. If the additive nature of accuracy and evasion were true, but there were no 6-level cap, the chance to hit would probably be 100% * 1/5 = 20%. If the additive nature of accuracy is fact and the total level cap is at 6, the chance to hit would then be 100% * 1/3 = 33.3%.

Out of 40 Gastro Acids, 15 hit and 25 missed. We might want a larger sample size to be sure, but it seems much more likely that the 6-level limit is in place than that it is not.

So, this discovery has a few implications. One is that if you have 6 Double Teams under your belt, lowering your opponent's accuracy levels through moves like Sand-Attack and SmokeScreen is pointless. It's probably not worth it to waste a moveslot on evasion boosting and another one on accuracy reduction.
 
Research on the Defense drops from Explosion and Selfdestruct:
Does Clear Body block the Defense drop from Explosion and Selfdestruct?
Metagross: 183 HP, 145 Defense, LV.54. My Clear Body Pokemon to be tested.
Weezing: 121 Attack. LV. 58. The Exploder.
Rhydon: 185 HP, 150 Defense. Lv. 55. Control group for comparing with Metagross.

Vs. Twins' Pachirisu:
Both Pachirisu Quick Attack Weezing and the first gets a crit. Weezing uses Explosion; it isn't very effective and does a little less than half Rhydon's HP in damage. Both Pachirisu faint.

One Pachirisu uses Bide, the other uses QA. Metagross uses Agility. Weezing uses Explosion. Metagross loses almost half its HP. It knocks out both Pachirisu.

Conclusion: Clear Body does not block the Defense drop from Explosion.
 
If I have a pokemon with only mimic and I use it to mimic last resort, will last resort work or fail??

If my pokemon is holding a sticky barb and is hit with embargo, is there still a chance that the barb will move to the opponents pokemon if the opponent uses only physical attacks?? (and isnt carrying an item, of course)
