guitarist- a guitarist greatest weapon his instrument.when he plays it he can start shooting lightning, fire and all kinds of other crazy stuff out of it. it cannot however be played indefinitely. you can only melt heads with your quick and rhythms for so long before your guitar overheats. after you melt a few heads with your power you can switch to an axe and start lopping them off.
bassist-a bassist keeps the rhythm of battle. he mainly is dealing out buffs and debuffs. a bassist can heal their allies but they have few offensive powers. as with the guitarist the bassist can only use the bass so much before it overheats. the bassist is better with conventional weapons than the guitarist.
drummer-a drummer always has the groups back. when the drummer sets down his drums he cannot move until he puts them away.with his drumming he can move earth and summon awesome summonings (for lack of a better term)((because i cannot think of anything better)). After all nobody headbangs to the rhythm of guitar its to fast, only to the drums.
