The Bestial domain was a deity domain that granted divine spellcasters like clerics with bestial spells and powers.
As well an assortment of bestial spells, these clerics gained much a heightened sense of smell, which could be used to track down or sniff out enemies.
Novice spellcasters were able to use the magic fang, bull's strength, and greater magic fang spells. Clerics of some experience could cast claws of the savage, charm monster, and hold monster. Those that were masters of this domain had access to whirlwind of teeth, spread of savagery, and were-doom.
