Are there any decent special-oriental Poison-types or any Pokémon that have the potential to put this move to fair use? If not, then it's potential wasted. T_T
The thing about this move is that it really doesn't make much of a difference even if you do get a berry activation right. Just look at this:
252+ SpA Life Orb Victreebel Sludge Bomb vs. 252 HP / 0 SpD Abomasnow: 400-476 (104.1 - 123.9%) -- guaranteed OHKO
252+ SpA Victreebel (
Belch) vs. 252 HP / 0 SpD Abomasnow: 410-486 (106.7 - 126.5%) -- guaranteed OHKO (no life orb because you used up a berry)
The only thing that I can truly see a benefit coming from this is that if you use a sweeping set, you won't have recoil as compared to the standard sets. However, considering both sets the life orb one is more powerful overall due to the fact that it also boosts up your coverage moves as well as your other secondary stab.
I do know how to make a belch set work though, 2 berries come to mind:
the kee berry and the maranga berry
Kee BerryRaises Defense if holder is hit by a physical move
Maranga BerryRaises Special Defense if holder is hit by a special move
Let victreebel use a maranga berry, as it could take a special hit much better than a physical one. Preferably, make it take a resisted hit that is not powerful enough to do any serious damage. The boost from the berry does not matter, the point is you activated it and can now spam a 120 base power poison move.
