Thick Skin

Thick Skin is a spell found in the ruins of Anodunos which allows the skin of the caster to harden significantly, which makes it much harder for blows from the enemy to cause injury. Essentially it is an addition to the armour of the mage. Note however that this is not the best protection spell available.

The spell Iron Flesh is superior to this one, although of course its requirements are higher as well. The weaker version of this spell is Resist Blows.
