Elemental Ward (Acid)

Your connection or exposure to powerful elemental magic has imbued you with primeval resilience. You gain the following benefits:

• Your Constitution score increases by 1, to a maximum of 20.
• You have resistance to acid damage.
• When a creature within 5 feet of you is subjected to an effect that deals acid damage, you can use your reaction to grant that creature resistance to that instance of acid damage. A creature that already has resistance to acid damage can't benefit from this feature. Once you have used this feature, you can't use it again until you finish a short or long rest.
