Camouflage: What you get in DP WiFi / Union Room
Building - Normal
Road / Desert - Ground
Grass / Tall Grass - Grass
Pond / Ocean - Water
Cave / Mountain - Rock
Snow - Ice
What you get from the terrains in PBR
Gateway - Water
Main Street - Normal
Waterfall - Grass
Neon - Normal
Crystal - Rock
Sunny Park - Grass
Magma - Rock
Sunset - Ground
Courtyard - Normal
Stargazer - Rock
Embargo: If a Pokemon is under the effects of Embargo and uses Pluck / Bug Bite, does it still immediately activate the berry, or is the berry just destroyed?
Encore: Lasts 4-8 turns. Is this an even distribution chance (as in 4, 5, 6, 7, and 8 turns all have equal probabilities)?
How to test: Use Encore, count how long it lasts. At least 15 trials should be good.
Heal Block: Does this result in Wish healing:
Fast Pokemon uses Wish
Slow Pokemon uses Heal Block
Fast Pokemon switches out
Slow Pokemon uses a move that isn't Heal Block
Does Heal Block prevent you from using Aqua Ring and Ingrain, or does it just block their healing for 5 turns?
Imprison: If I have a Smeargle that knows Imprison, Hyper Beam, Transform, and Fly, and I use Imprison, then Transform into a Geodude with Magnitude, Tackle, Hidden Power Poison, and Explosion, and my opponent then switches into a Pidgey with Tackle, Hidden Power Poison, Hyper Beam, and Fly, can Pidgey...
a) not use Hyper Beam and Fly, but can use Tackle and Hidden Power
b) not use Tackle and Hidden Power, but can use Hyper Beam and Fly
c) not use anything, or
d) use anything
Basically, if you get new moves, are the new moves Imprisoned? Another way to test is ti Imprison, use Sketch or Mimic, and then see if the Sketched / Mimicked move is Imprisoned and if Sketch / Mimic is Imprisoned.
Ingrain: What happens if you U-Turn while under the effects of Ingrain?
Lucky Chant: Is Lucky Chant lost by switching?
Magic Coat: Can you Magic Coat Heal Block?
Mimic: What can't it select?
Mist: Does it block Haze, Heart Swap, Power Swap, or Intimidate?
Nature Power: Has some new moves chosen for the various arenas in DP:
Road / Desert = Earthquake
Building = Tri Attack
Grass / Tall grass = Seed Bomb
Cave / Mountain = Rock Slide
Snow = Blizzard
Pond / Ocean = Hydro Pump
Note that in WiFi / link battles, only one attack can be chosen, and that's Tri Attack.
In PBR:
Gateway - Hydro Pump
Main Street - Tri Attack
Waterfall - Seed Bomb
Neon - Tri Attack
Crystal - Rock Slide
Sunny Park - Seed Bomb
Magma - Rock Slide
Sunset - Earthquake
Courtyard - Tri Attack
Stargazer - Rock Slide
Pursuit: Does Pursuit against a faster U-Turner still have a chance to hurt itself in its confusion (assuming the Pursuiter is Confused, of course)?
If a Pokemon holding a Choice Band / Choice Glasses / Choice Scarf uses Pursuit against a Pokemon switching out (and ONLY against a Pokemon switching out), they can no longer reselect a different move next turn, even if this happens on the Choice item holder's first turn in battle. They can change moves in the Japanese version of DP, but in cross-language battles, the English version's settings override it.
Safeguard: Does Safeguard prevent a Pokemon from being Poisoned by Toxic Spikes? If Safeguard is up and a grounded Poison type switches in, does it still absorb Toxic Spikes?
Secret Power:
Road / Desert = Lowers Accuracy 1 stage
Building = Paralyzes
Grass / Tall grass = Sleep
Cave / Mountain = Flinches
Snow = Freezes
Pond / Ocean = Lowers Attack 1 stage
Note that in WiFi / link battles, the only available stage is Building, so you only can Paralyze with Secret Power there.
Secret Power in Battle Revolution:
Gateway - Lowers Attack
Main Street - Paralyze
Waterfall - Sleep
Neon - Paralyze
Crystal - Flinch
Sunny Park - Sleep
Magma - Flinch
Sunset - Lowers Accuracy
Courtyard - Paralyze
Stargazer - Flinch
Substitute: Does Heal Block hit through Substitute?
Tickle: No longer hits through Substitutes.
Toxic Spikes: Does Safeguard prevent a Pokemon from being Poisoned by Toxic Spikes? If Safeguard is up and a grounded Poison type switches in, does it still absorb Toxic Spikes? Does a grounded Poison that is Baton Passed a Substitute still absorb Toxic Spikes?
Twineedle: Contrary to popular belief, it cannot Poison Steel types.
Pokemon cannot die to Poison outside of battle. If they are taken to 1 HP and are supposed to receive more walking damage from Poison, they are cured of Poison and receive a message saying so.
