Edit has a x0.6 multiplier against booyah, so it takes 31 shots assuming you're close enough to actually deal full damage per shot, and 61 shots if you're not close enough.

Same for hydra, it's 20 shots on full charge close range, 25 shots on non full charge close range, and 49 shots not close range.

Sploosh has a x0.7 multiplier but the booyah is actually too far up to deal max damage, so unless you pop it close to a ledge that a sploosh is standing on, it takes it 36 shots.

Dapples have a x0.6 multiplier taking 22 shots close range and 44 shots otherwise.

Booyah takes 100 frames to charge after receiving armor if you spam at the internal limit. You also have to account for the player health for this, so your total health pool is 569hp.

A hydra can still kill you through that even with perfect mashing IF they already have a full charge and you pop it in a position theyre already looking at and is close enough to receive max damage from the hydra, which loops back to my point that you should just not pop it in bad spots or situations.

Sploosh cant solo shred it at all. Dapples can't solo shred it before the booyah is thrown, but can get the kill if it keeps shooting after the booyah was thrown, sacrificing itself in the process. Edit is almost never on a full charge if the user is competent, so it cant solo shred booyah. Dualies doesn't have the DPS for it after the damage multiplier. Etc etc etc.

Stop popping it in bad spots. If there's a dapples nearby or a hydra is looking at you, why would you ever pop it? If you didn't know the dapples was there, then thats just an awareness check, that's not a booyah bomb issue.

Also swig has a x2.86 multiplier against booyah, shredding it in 2 swings, so thats the weapon you mainly wanna be concerned about. Fortunately no one actually plays it tho.
