The changelings blessed with it can, once per day as an instant action, spend one point of Glamour to harden the character’s skin, making it like rock. The character uses his Wyrd as his armor rating for the rest of the scene. The character’s rocky carapace does mean, however, that the character isn’t as nimble as he was: the changeling suffers a –1 die penalty to all Dexterity-based dice pools while this power is active. In addition, his Defense is reduced by one for every two points of Wyrd past the first; –1 Defense at 3 Wyrd, –2 Defense at 5 Wyrd and so on. This blessing doesn’t stack with mundane forms of armor.
