Critical Empowerment

When you gain this feat, choose one of the following damage types: acid, cold, fire, lightning, necrotic, poison, psychic, radiant, or thunder.

When you deal the chosen damage type as part of a critical hit, any creature affected by the critical hit comes under the relevant damage condition until the end of your next turn. Additionally, while a creature is affected by the condition, any attack against that creature has advantage if the attack would deal the condition’s damage type.
