Hardens the caster's skin. It has no effect on the undead or those under the effects of most types of transformation.

Stoneskin is a level 2 Earth Magic/Transmutations spell which temporarily makes the caster's skin hard as stone.

Useful Info

Stoneskin grants a temporary bonus to AC:

AC Bonus: 2 + (power/20)
Max: +7

Each casting increases Stoneskin's duration by 8 + 2d(power) turns, up to a maximum of 50.

This AC bonus stacks with Statue Form, but it can't be combined with Ozocubu's Armour. It does not work with most form spells; only Beastly Appendage, Blade Hands, and Statue Form work with Stoneskin. The undead (Ghouls, Mummies, Vampires below Full) can't use this spell.

Strategy

A weaker version of Ozocubu's Armour, without encumbrance restrictions, that doesn't melt against fire. If you can cast Stoneskin (but not Ozocubu's), it's generally worth using - either during exploration or at the start of every fight.

Note that Stoneskin will not notify you when its duration is almost over. Should you be in the middle of a pitched battle, consider casting it again when you have a spare turn to guarantee you maintain your AC bonus until the end of the fight.
