Spells: Gravity flux hitting caster no matter what

[DMN]

for whatever reason gravity flux seems to hit the person who casts it if they are in the AoE, even if the cast it in the middle of 4 mobs.

tested it
4 mobs + caster in range = caster hit along with 4 mobs
5 mobs + caster safely out of range = 4 mobs hit hit. none hit caster
