Favor

By casting a favor spell, the priest asks the deity to watch over the recipient. Usually, the favor spell is cast upon a great hero, such as Odysseus or Jason, just before the hero undertakes a magnificent deed.

The effectiveness of the spell depends upon how the priest's god views the glory of the deed to be undertaken. Usually, as the god's favor is somewhat arbitrary – this is determined by rolling 1d6. For the duration of the spell, the recipient's saving throws are modified (in the positive direction) by the result. In cases of especially glorious undertakings, the DM may assign a saving throw modifier.

In addition, the subject is blessed by a pledge of one godly intervention. In practical terms, this means that, during the duration of the spell, the subject can reroll any single die roll that affects him or her personally. The recipient invokes this pledge of intervention only once, even if the second roll was unsuccessful.

The gods never grant more than one favor spell to a single group of adventurers or a single adventurer, and usually insist that the spell be cast upon the group's leader. If a second favor spell is attempted, both it and the first are lost.
