When it reaches 100%, you instantly explode unlike other warp related overcharges where you stumble a bit to save yourself.
The stun on the staff seems really inconsistent with Mutants. It takes like half a second for the stun to take effect whereas every other non boss enemy gets stunned the moment it makes contact and sometimes the mutant just isnt stunned at all despite numerous attempts.
The staff is vertically challenged. The staffs alt fire will not connect with targets too far below or too far above you despite being mere inches away.
