The beta patch notes for 1.2 are out:
Lots of changes to Lord Darrens Voulge
I do not understand what all of these changes mean,, but probably we have to say goodbye to the suicide bomber.
I think you won't be able to damage yourself anymore. Also the helm was nerfed and it's not possible anymore to stack multiple charges.
Yeah you are right, first since the Static Thunder only works when u have stacks, so you cannot hurt yourself with it, secondly the helm only works on big elec damage now because it is not stackable, so very sad indeed
