Sap

A sap spell coats everything within the area of effect in tree sap. After the spell is cast, any creature entering the area of effect is slowed to half its movement rate while in the affected area. Any creature in the area of effect when the spell is cast must make a successful saving throw vs. spell or be covered in the sticky substance. Those who succeed can reach the nearest unaffected surface by the end of the round, although their movement rate is also reduced to half normal while within the area of effect. Those who fail their saving throws have their movement rate reduced to 1 and have their Dexterity reduced by half. Casting spells, employing magical items requiring any sort of movement, or any launching any sort of physical attack is impossible while under the effects of this spell. In addition to any loss of Dexterity bonus, the creature incurs a +2 Armor Class penalty (to a maximum of AC 10). Winged creatures and those employing magical items such as wings of flying cannot fly.

A free action spell or ring or similar effect negates the effects of a sap spell for the affected individual only. Thoroughly dousing an individual covered in sap with wine also ends the effect.

The material components are the priest's holy symbol and a drop of tree sap.
