[Chaos]

I should mention that there's a certain suggestion in the Offensive Spells topic that touched upon Needle:

Needle:
-Replace static damage with Light ATK
Light ATK: 10% -> 20% -> 30% -> 40% -> 50%
-Needle Explosion effects use (20*Rank)% Light ATK
-With 2~3 Round Cooldown, reduce M cost to 3M
REASON: Thanks to RES now factoring in, Needle needs a more fitting damage boost. Secondary effect was extremely minimal as well, due HP taking on larger numbers than before, and needed a better boost.
