Irritation

An irritation spell affects the epidermis of the subject creature. 

Creatures having very thick or insensitive skins (such as buffalo, elephants, scaled creatures, etc.) are basically unaffected by the dweomer. There are two versions of the spell, either of which can be cast from the standard preparation:

Itching. When cast, this causes the subject to feel an instant itching sensation on some portion of its body. If 5-8 segments are not immediately spent scratching this irritated area, the subject creature will be so affected that the next 3 rounds will be spent squirming and twisting, effectively lowering the subject's armor class by 4 and its "to hit" probability by 2 during this time. Spells are ruined for the initial round this spell is in effect, but not for the following three rounds.

Rash. When a rash version of the spell is cast, the subject creature will notice nothing for 1-4 rounds, but thereafter its entire skin will begin to break out in red welts which faintly itch. The rash will persist until either a cure disease or dispel magic is cast upon it. It lowers Comeliness by 1 point per day until four days have passed, i.e. maximum loss of Comeliness is 4 points. After one week, the subject's Dexterity is lowered by 1 point also. Symptoms vanish immediately upon the removal of the rash, all statistics returning to normal.

The material component for this spell is powdered leaf from poison ivy, oak, or sumac.
