Fiendish Transformation

Take on a demonic aspect: horns, claws, wings of smoke, burning eyes, shadow-hide, or a tail. For the duration, gain resistance to fire and necrotic damage, your Eldritch Blast and Pact Blade deal extra damage equal to your CHA modifier once per turn, and you have advantage on Intimidation checks.

This power has its own stable page so it can be linked from any character, item, location, story post, bargain, curse, or future reward.
