Mist elves wearing iron rings - inconsistent behaviour
Mist elven wizard started the game with two identical rings of mental stability (wiki says it is made of iron).
If she puts on one, she can wear it properly with no negative effects. If she puts on two at the same time, she starts to get damage with the usual "Your skin is destroyed by the touch of impure metal".
Since it is a starting character, she has no damage-reducing talents.
