Over on the Paizo boards, there’s a thread wherein people wonder why Cayden Cailean doesn’t have the Liberation domain. (I’m not sure why people kept talking about it after I won the thread with my first post in it.) Early in the thread, poster Tilquinith typed, “I wonder what sort of domain powers would be granted by Libation?”
Well, wonder no more!
Granted Powers: You can augment your spells with a libation. A libation is a pouring out of wine or other liquid in honor of your deity.
Libation (Su): If you pour out a libation as part of the somatic and material components of a cleric spell that you cast, that spell takes effect as if your caster level were one level higher than it actually is. You can use this ability a number of times per day equal to 3 + your Wisdom modifier. A libation costs at least 10 gold pieces and weighs 1/2 pound.
Greater Libation (Su): At 8th level, your libations increase in power. In addition to boosting your caster level, your libation also applies one of these metamagic feats (chosen at time of casting) to your spell with no change in the spell’s effective level: Bouncing Spell, Disruptive Spell, Ectoplasmic Spell, Elemental Spell, Enlarge Spell, Extend Spell, Flaring Spell, Focused Spell, Intensified Spell, Lingering Spell, Piercing Spell, Rime Spell, Silent Spell, or Toppling Spell.
Domain Spells: 1st—bless, 2nd—blessing of courage and life, 3rd—prayer, 4th—blessing of fervor, 5th—cleanse, 6th—heroes’ feast, 7th—greater restoration, 8th—euphoric tranquility, 9th—mass heal.
