Divinity Shard of Flames

Awaken the Primal Flames of Divinity, upon slaying the previous wielder of this feat you gain access to the following abilities:

• You gain immunity to fire damage and when you would take fire damage you instead regain that many hitpoints.
• You ignore resistance to fire damage.
• When you would deal damage, you can choose to deal an additional 4d6 fire damage to the creature that you are damaging.
• When you are hit with a melee attack, the attacking creature takes 2d6 fire damage.
• Once per long rest, you can conjure an efreeti within 100 feet of you for 1 hour or until it is reduced to 0 hp. After the creature is destroyed or time runs out, it is safely returned to its plane of origin. You always summon the same efreeti to aid you, therefore it is always friendly to you and your allies.
