From a strict chemical sense, Holy Water is no different than ordinary water. However, Holy Water has been blessed with the spiritual presence of the God of Good and thus has a caustic effect against denizens of the Undead and the constructs and practitioners of evil powers. The table below displays the damage inflicted against supernaturally evil creatures.
Table: Effects of Holy Water versus Evil Creatures | |
Creature |
Damage |
Incorporeal Spirits | 1d2 points damage to Willpower |
Possessing Spirit | 1 point of damage to Willpower |
Summoned Creature (evil alignment) | 2d4 points damage to Hit Points |
Undead | 3d4 points damage to Hit Points |
An attack of holy water can be used just once against a possessing or incorporeal spirit. But against demons and physical Undead, multiple applications can yield multiple damage.
If a character of good alignment drinks a vial of Holy Water, he of she receives one hit point of healing. This benefit can be received only once per day.
Holy Water retains its properties indefinitely if stored in a specially consecrated vessel or font. If kept in a container fashioned from silver, the liquid retains its properties for one week per level of the Priest. If stored in an ordinary container, the Holy Water remains effective for only one day per level of the Priest. For combat purposes, a "dose" of Holy Water is three fluid ounces.
