Wouldn't a bomb that you could use to directly strengthen your teammates be cool? Kina like the alpha wolver. Charge the bomb, put it down, and anyone in the radius will deal more damage for a while or have temporary added defense.
A bomb that dosent go off untill an enemy steps on it would be great. Especialy for kiteing knightbots on those deep arenas. If it had knock back, you could set a couple and watch the monsters bounce around. I guess it could just go off on it's own after awhile.
uhh no thanks on the buff bombs and the land mines are too conditional u would need to navigate the monsters to it
