Your gaze attack for Mirror of Misfortune is... terrifying. 1d4
drain to three mental stats? That's... devastating. At 8th level (cleric 7/Sybil of the Blinded Eye 1) you can permanently handicap spellcasters. I'd save that for a higher level ability if you want it to be drain or change it to
damage (which is what I'm hoping you meant) which can be healed by restoration effects. Still potent enough to handicap a caster, but not a permanent drain ability at 8th level. I think all of your Mirror abilities should be changed to damage instead of drain, personally.
