>>28518672No, several bosses have over 1k HP. This makes multi-hit moves even better in comparison to normal moves than usual, provided you're so buffed you're hitting 999 regularly, which I find isn't the case in Super.
I only ever hit 999 on my games with Chespin/Mega Ampharos/Buizel with crits and a good set of emeras backing me up.
Rollout can/will oneshot postgame bosses since it gets more powerful with each hit, hits 5 times, will always hit 5 times provided it has enough accuracy. This is as opposed to other multihit moves which have their number of hits decided by RNG but can keep hitting even after one of the hits misses.
This is why Chespin is so good at oneshotting or at least utterly destroying postgame bosses.
