Powershot is the most powerful skill available to bow type scouts and is also more powerful than all other dagger type moves a scout has (other than punishing strike). It has a slow start up so using it requires a still opponent, lucky shot, or well aimed lead; although it is a faster startup than piercing shot. This skill is useful to finish off weakened players and can also mean the difference between winning and losing in one on one fights between you and your opponent (unless that opponent is a warrior with more than 300 hp. then you're screwed.) I find this skill a favorite when hitting slow summons such as chimeras and giants while evading the majority of any attacks thrown out.
