For reference:
Charge [A]: After Moving, immediately fight a combat against an Adjacent model. Cast two additional Combat Stones. Neither side can benefit from support. This ability cannot be use if the model had to Move Cautiously.
Flit [C]: This model may move up to 3” in place of its combat action.
Evasive [T]: Each successful Oran cast by this model cancels two opposing Erac.
Flying [T]: This model may move over enemy models as long as it has sufficient movement. It may also move at full rate even if forced to move cautiously.
