Demon Form

Demon Form is turned off when Living Bomb is cast. Living Bomb has spell tag, so unless there is another reason it is being turned off when casting Living Bomb, it is not written out in game text.

living bomb is a weapon spell skill & demon form is currently similar to 'unarmed' in that it doesn't use your weapons, so when you use a weapon skill, you drop demon form.

i vaguely recall ggg commenting about revisiting that in the future but idk the exact wording.
