Tyr's Ring of Sacred Wrath

As a Standard Action, the wearer may mark off one use of the cure light wounds Spell to instead deal 5 Sacred damage to one target. There is no hard limit on the number of times this ring’s power can be activated, but each time it’s used the player must first mark off one use of cure light wounds.

The caster may apply their total Spell Damage Bonus to this effect, but not their Healing Bonus as this is no longer a healing Spell, it’s become a damage Spell

Note: Undead suffer double damage from any source of Sacred energy, but Good-aligned Outsiders take no damage from Sacred power. If an attack with added Sacred damage wounds an Undead creature, only the Sacred portion of the damage is doubled.
