You are blessed by one of the gods and can empower their cult’s Miracles. Upon learning the Talent, you gain one Miracle of your choice from those available to your patron. You may now memorise additional Miracles from those available to your patron for the following cost in XP.

Under normal circumstances, you may not learn more than one Invoke (Deity) Talent. Further, you may not learn the Channelling Skill or the Arcane Magic, Chaos Magic, Magic Resistance, Petty Magic, or Witch! Talents when you have the Invoke Talent, and vice versa. You can unlearn this Talent for 100 XP, but will lose all of your Miracles if you do so, and will garner the extreme disfavour of your god, with effects determined by your GM.
