I believe this spell to have an insanely cool idea but lacking in it's execution, to my understanding, it's meant to be a damage focused spell but it ends up being a weaker gun on a cooldown..
- my main problem with it: you have put away your weapons to use what's in most cases, a weaker one. i don't think it's powerful enough to justify swapping your main weapons to it, especially considering it's cooldown, it has okayish AOE and leaves elemental puddles but that's about it :/.
i think the spell nulls everything out
