question about some spells and durability

[frostbolt]

would casting spells like weaken, feeblemind, and other debuffs on myself to train resist spells cause me to lose durability on my armor?

I don't think so. I think you actually have to be beaten on by something to lose durability. I cast on myself all the time (for training purposes) and have never lost durability.
