You are watched over by one of the gods and can empower simple prayers. Upon learning the Talent, you manifest all the Blessings of the deity you worship.

Under normal circumstances, you may not learn more than one Bless (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 Bless Talent, and vice versa. You can unlearn this Talent for 100 XP, but will lose all of your Blessings if you do so, and may garner the disfavour of the god you have spurned, with effects determined by your GM.
