Wondrous Item, uncommon (requires attunement by a Spellcaster)
While attuned to this apparatus, all spells you cast that deal Cold, Fire, Lightning, Thunder, Radiant, or Necrotic damage instead deal Acid damage. Additionally, when you cast a spell that is affected by this apparatus and that can only target one creature, you may add your Spellcasting modifier to the damage rolled.
Notes: Spellcaster, Buff
