Hmm... That's definitely neat and poses an interesting question then:I also did more research on multi-hit moves, and it turns out that each hit will activate whatever reactive ability it's facing multiple times. For example, against Breakable Armor, if I hit it 4 times with Arm Thrust, the opposing Pokemon would sit at +4 Spe, -4 Def -- the ability activates each time the Pokemon is hit. From all my tests with multi-hit moves, I think we can draw the conclusion that in this gen, each hit is treated as separate attacks which are contingent on the previous hits successfully making contact. Pretty neat.
-Does a Pokemon still take Life Orb damage only once for a multi-hit move, as in Gen IV, or does it now take 10% damage each time it hits the opponent?
