I like it!

Converting the Mote system into a power-by-round effect instead of a larger pool with limited recovery per round is a good idea. It reduces the amount of book-keeping players will have to keep, and encourage them to use Illuminations as often as possible.

Having the base pool set at 2 * class level seems a bit high though. A level 5 character could blow 5 points on a 5d6 Blast with the Chaining quality (potentially hitting another target for 3d6 damage), then spend a Move action to get 15 points of Temporary hit points for 1 round from the Vitality Barrier. It certainly outclasses most of the things a Warlock of that level could to, and it pushes the limits of what your average 5th level Wizard could accomplish in a round, Fireball or no.

Overall, I think it's shaping up very nicely. I'm definitely waiting for the Empath and Zodiac classes - I really want to play an Illumination specialist that ditches hit points and costume effects for Giant Orbital Friendship Cannons.

Because FRIENDSHIP.
