Vicissitude

This spell allows the cleric to bend fate, but not without risk. When faced with any situation involving chance the cleric need only make the mystic passes of this spell to receive a +10% bonus to the die roll, (cf., stone of good luck).However, each time this spell is used there is a non- cumulative 5%chance that it will backfire and produce the worst possible result for the caster.
When applied to saving throws, this spell grantsthe cast- er a +2 bonus to the die roll (aroll of “1“always fails),but if a natural “20” is rolled, disaster strikes and the cleric suffers maximum damage from the attack.
The cleric must be alive to use this spell and must have Ralishaz’ three bone holy symbol openly displayed.
