Draw upon holy might

Draw upon holy might was a spell that would turn the priest's body into a vessel of the priest's deity. The priest would gain power and glow brightly. It was one of the spells available from the Balance of Belaros, a holy relic of Tyr.

Effects
With this spell, the priest drew upon power from their deity. The caster could choose to become more strong, dexterous, or charismatic. After the spell effects had worn off, the priest would be incredibly drained, both in mind and body. It would only affect the caster.

Components
The spell required verbal and somatic components. It also required two material components: a vial of holy water that had been blessed by a high cleric, and the priest's holy symbol. These items must have been from the same faith as the caster.
