Like all +2 weapons, the DM adds +2 to the AC hit when using this weapon but the damage bonus has already been factored into the damage wheel.
This weapon’s damage is comprised entirely of Sacred. If a character equips other tokens that increase damage, all un-typed damage bonuses deal their damage as Sacred, but typed damage bonuses retain their original type. E.g., a character with a high Strength score coats this weapon with Oil of Venom.
