Definitely a more utility-based dps. I like the juggling of physical and magic damage debuffs and then the consumption of them using checkmate. It's an interesting combination of blackmage and arcanist mechanics that I think would work well.

I would like to simply make the MP regen on Mage Masher a plain 60 potency regen though rather than basing it off damage. It'd be simpler to code and would still allow regen if the target is invulnerable (just a loss of dps, which is reason enough for a dps not to use it).

Otherwise, great job and I hope to see more on how the Sharlyans story works out for this class.
