Stoneskin (spell)
Stoneskin improves the recipient's base armour class to 0 (zero) for the duration of the spell. Armour class bonuses for Dexterity and armour (if worn) would then apply to the character. Thus, if the recipient of the spell were to wear chain mail, which offers a +5 armour class bonus, the recipient with stoneskin would have a total armour class of -5.

| Duration | 1 round per level |

| Casting Time | 2 rounds |
| Saving Throw | none |
| Level | mage (4th) |
As well, recipients of the stoneskin spell are entitled to choose to make saving throws against certain attack forms as they affect objects, if these saving throws are an improvement over the character's normal save chance. The attack forms affected are (with their saving throws): acid (3); fireball (5); magical fire (3); normal fire (2); frost (1); lightning (14); and electricity (2).
Thus, for example, if the recipient were a 7th level mage, with a normal saving throw of 10 against fireball, he would in fact have a saving throw of 5 while influenced by the spell.
