Champion's Strength allows the priest to draw strength from his god and lend it to an ally.
|“|| Champion's Strength|
When this spells is cast, the priest effectively draws on the strength of his god and lends it to the target creature, in effect creating a champion. The target gains a bonus to his THAC0 at a rate of 1 for every 3 levels of the caster. So a 9th level priest would confer a THAC0 bonus of 3 to the target, and so on. Also the target's Strength is set to 18/00 for the duration of the spell and receives all the bonuses to hit and damage rolls that this Strength confers. Note also that if the target's strength is above 18/00, it will actually be reduced to this value.
The drawback to this is that the priest must concentrate on the connection between the target and his god for the duration of the spell, hence losing the ability to cast any spells during this time. The effect lasts for 3 rounds for every level of the caster or until dispelled.
