Ring of the Savant

When casting a Spell that requires a skill check, if the wearer succeeds on the skill check, the Spell deals +5 damage if it’s a damage-inflicting Spell, or heals +5 HP if it’s a healing Spell. The bonus provided by this ring is not subject to modification and is added after all other bonuses are calculated. This ring does not affect Spells with no skill check or Spells that neither damage nor heal. This ring does not affect scrolls, wands, or items–even ones that require a skill check.

If the Spell can affect more than one target, the caster gets a pool of 5 damage/healing to allocate among eligible targets.
