Iron Body (3.5e Spell)

This spell transforms the body of the creature touched into iron, granting them all the properties of such while also making them stronger and heavier and allowing them to shed the weaknesses of the flesh.

The subject gains DR 15/adamantine. They also become immune to the following: blindness, critical hits, ability score damage, deafness, disease, drowning, electricity, poison, stunning, and all spells or attacks that affect physiology or respiration. They take only half damage from acid and fire of all kinds. In return, they are vulnerable to all attacks or effects that particularly affect iron golems.

The subject gains a +6 enhancement bonus to their Strength score and a slam attack that deals damage based on size(1d4 for Small characters, 1d6 for Medium, etc.). This slam attack has a flat enhancement bonus of +1 per three caster levels. While under the spell's effect they do not need breathe but cannot consume food or drink (and thus can’t use potions) or play wind instruments.

The target's weight increases by a factor of ten, halving their speed and causing them to sink in water like a stone. While in this form, however, they suffer no ill effects from being submerged no matter how deep they go.
