Rori has found his base form - completely removes mirror shifting and malleable form abilities.
Also removing references to shifting in physiology
As a result of achieving his base form, would like to add.
Transfiguration Resistance - Having achieved his base form, Rori's body is unwilling to give it up. It reacts to any magic that changes his form (transmogrification, glamour. Not acid based or disintegration magic) the same as an injury, by regenerating. This is at the speed of his natural regeneration, an inch every five minutes, so assuming his entire body was changed, it would take him about 6 hours to completely change back. Wearable glamours give him migraines and make him feel achy and tense as a result of his body attempting to fight them off. He cannot control this ability or shut it off.

Physiology - Ageless. His hair doesn't grow naturally except as part of his shifting. Can regenerate limbs at about an inch every five minutes. Cannot regenerate his head - decapitation will kill him. Wouldn't be permanently injured by piercing or pressure. Doesn't bleed. Rori's "skin" is about an inch thick and he's completely hollow inside. His teeth and nails are only slightly firmer than the rest of his flesh, and couldn't be used to bite/scratch, even if they shifted into something like claws.
