Amulet of Elemental Adaptation

When you attune to this item, pick an elemental damage type (fire, cold, thunder, lightning, acid, poison). Once you pick this type, all spells you cast/damage you deal that is one elemental damage now deals your selected damage type. (EX. Burning Hands or a Flame Tongue Dagger now does cold damage if you selected cold as your new damage type.) This can only be changed by a wish spell or similar. You also now negate any resistance or immunity that a creature has to your selected damage type.

Notes: Damage, Buff, Jewelry
