Elemental Expertise (5e Feat)
From D&D Wiki
Prerequisites: The ability to cast at least one spell, Elemental Adept
When you gain this feat, choose one of the following damage types: acid, cold, fire, lightning, or thunder.
- You gain resistance against the chosen damage type. If you already have resistance, you have immunity against the chosen damage type instead.
- When you cast a spell that deals the damage of the chosen type, you ignore the target's resistance to the damage type. If the target is immune to the damage type, it is considered to have resistance instead of immunity against your spell instead.
You can select this feat multiple times. Each time you do so, you must choose a different damage type.
