make a ability so and u can activate it up to 3 times, 4th disables ability:
once will spawn a hydra connected to u and will attack instead of u punching when m1 also leaves a small poison trail
twice will just be the same but more poison dmg more dmg and bigger posion trail
third you get the idea
fourth will summon them back into u
also make it so the ability where u shoot a ball can be changed by crouching to make it shoot 5 instead of 1
