If Mana Shield needs changes it should be on the nerf side because 80% damage reduction is ridiculous. This is, to an extent without reforges as well. (with enough MATK you can push it to near 90%)
It's balanced atm because only mages can get that damage reduction at the cost of suffering more chip damage due to no def/prot, and requires lots of MP pots to sustain it
No I'm asking how is yours reducing 80% damage?
