At level 1, bisexuals can only wield on finger gun. Upon reaching level 5, bisexuals gain the ability to dual wield finger guns, with a small accuracy decrease.
@katherine at level 20 bisexuals gain a third finger gun, but the rules are unclear on how exactly this works
@squeedoodle @katherine i generally interpret it as meaning we get to extend an additional finger on one of the hands doing a finger gun, for double-barreled finger gun. i don't personally know of anyone who's reached a high enough level to have unlocked dual-wielding double-barreled finger guns, but it seems induitive that the bonus should eventually become available
