Celtic Heroes

I use it all the time; particularly helpful when a boss is raged and you don't want you/certain DPS to get aggro (and therefore survive). Even at level 1, it works great at Gele and Proteus.

My calm is 10 with a 9 hot swap ring. I don’t calm anyone but me as I get too much aggo, save the person I’m helping, then die.

I use it on myself, even with only 1 pt it's helpful to redirect aggro back to tank.

I use it to get mobs off me (Hotswapp one of the old +10 charms and an aggy ring) which happens a lot since I'm hybrid.
