Chakra or Shield Mastery?

I don't use pineappleing Chakra to survive o_o

I meant it more as in "Especially when you're using it -and want to- survive"

Chakra is all about the minimum HP it heals (it has 50% mastery). So a higher lvl = higher minimum heal amount.

Also, don't forget that the reduced damage bonus is only good at max level Chakra.
