Raid damage at level 40, 15/15/15 IVs, no weather boost.

DPS is damage per second, TDO total damage before fainting. For one boss, see the raid counters.

Don’t Use means repeating the fast move does at least as much damage as using this charged move, either because the move is weak or because this Pokémon faints before it pays off.
