@RiptideFugitive:
If you BP a Sub to a Pokemon, and the Sub's remaining HP is greater than that of that Pokemon's max HP, OHKO moves will not destroy the Sub. It will only do as much damage as the Pokemon's max HP.
I got some commentary from Footnote, who AIM'd me while I was out grocery shopping:
[19:29] LastFootnote: No need to respond. I just have a couple of comments about the research thread.
[19:30] LastFootnote: First, your info about Encore in the second research thread is inaccurate.
[19:30] LastFootnote: If you're encored in 2v2, you are forced to pick a random opponent to target. *You will not necessarily keep targeting the same foe. *It worked this way in Advance, too.
[19:31] LastFootnote: Second, you all should really make sure that OHKOs are even affected by Gravity's accuracy boost before using Fissure to test how much the boost is.
[19:32] LastFootnote: That is all. Hope you're doing well.
[19:40] LastFootnote: Actually, I lied. That's not all. Frisk chooses a random opponent in 2v2 and Razor Fang has a chance to flinch for each hit of a multi-hit attack (Beat Up with 6 Pokémon has about a 50% flinch rate).
Although we've already determined that OHKOs are unaffected by evasion\accuracy modifiers including Gravity, Footnote is right about Encore - I totally screwed up the interpretation of my findings.
Drifloon uses Payback on enemy Machop last turn.
Next turn, Drifloon targets ally Wobbuffet with Payback.
Ally Wobbuffet uses Encore on Drifloon.
Drifloon uses Payback on enemy Machop instead.
This was what occurred in a battle I had. Now, one could interpret this as Encore forcing the target to instead target the Pokemon it last hit before it was Encored - this is the mistake I made. Or, it could be possible that Encore forces the target to
instead target an opponent.
Footnote realized this, and he seems to be right about it. After Encoring my own ally Breloom's Spore, I found it would target only random enemies.
On a side note, Acupressure doesn't target random Pokemon on your side if it gets Encored. It does lock you into Acupressuring the target you chose the turn Encore went off. Also, Acupressure doesn't work if your target has a Substitute up - whether it's your ally or yourself. This puts a real damper on my Surf\Acupressure\Confuse Ray\Substitute Tentacruel...
As for Beat Up + Razor Fang, I'll look into it.
