Storm Hammer isn't working properly

[StormGirl]

EUREKA! I did an experiment and found out not even the prototype kills the thing in one hit. Conclusion: Two headed creep is a tough nut to crush

But mine does. O-0 What prototype do you have? I have the prototype-up1. I quickly switch to it from my hammer, to kill this 2 headed zombie in one shot.

Normal because I got bankrupt in the game
