This spell transforms your body into living iron. You gain damage reduction 15/adamantine. You are immune to blindness, critical hits, ability score damage, deafness, disease, drowning, electricity, poison, and stunning. You take only half damage from acid and fire of all kinds. You gain a +6 enhancement bonus to your Strength score, but you take a -6 penalty to Dexterity as well (to a minimum Dexterity score of 1), and your speed is reduced to 50% normal. You have an arcane spell failure chance of 50% and a -8 armor check penalty, just as if you were clad in full plate armor. Your unarmed attacks deal damage equal to a club sized for you (1d4 for Small characters or 1d6 for Medium characters), and you are considered armed when making unarmed attacks.
