Mystic (MST)
Damage Reducing Off-Healer which has the same function as : SCH - Damage Reducing Off-Healer

Sorry but I don't agree with it because that's what scholars do already.

corruption" doesn't fit the class identity as a healer

Delirium" is already in use by DRK... etc etc

You are almost copying AST with "attunement system" Diurnal/ noct Sects, make your ideas unique.

Yin and yang doesn't work either because those names are already taken by NIN....

Is the game really that boring for you that you need to jumble a bunch of abilities sch and ast already have ?
