Such a broken spell. You know those powerful knight-cleric that has a huge *** weapon (and AR) like 1000 HP and about 50% resist to everything? Yeah just hit him with this, which is since the spell range is longer than his aggro range, in one quick cast.
Now change your equipment (as he patiently stands there) to either farming gear or recovery gear (IE focus regen on critical hit) and stab him to bits. Turns the toughest non-boss enemies into pinatas.
And that's not even taking into account pitting them against each other! Normally facing 2 Lotric Knights at once is nigh-hopeless, but cast this, then hit the survivor with a feather and GG you win.
It's like From accidently incorporated a cheat code into pyromancy.
