Your fists turn into menacing, rocky lumps capable of inflicting deadly wounds. While this spell is in effect, your unarmed attacks do not provoke attacks of opportunity, & they deal lethal bludgeoning damage. The damage that your unarmed attacks deal increases as well, according to your size as given on the table below.
[Table not included/necessary at this point]
If your unarmed strike already deals more damage than the indicated amount, you always use the higher value. In addition, if you are a dwarf or goliath under the effects of this spell, your unarmed attacks overcome damage reduction as if they were cold iron weapons.

Unarmed strike is used only once, & that is when the attack/strike is referenced in the singular.
