ACENTRIC BLAZE

The Hag Mother has granted you affinity with eldritch magic and your ability with your pact weapon nears mastery. Using an action, you may active acentric blaze and gain the following benifits that last for 30 seconds. This feat can only be used once per long rest. 

Your body starts to emit eldritch fire that adds +2 to your AC.

If the dash action is used, the ground you pass over is ignited by eldritch fire and deals 2d8 damage to any creatures that passes through it.

At the cost of a bonus action the user may immulate their form with eldritch fire. Any creature within 10ft takes 3d10 fire damage. If a Dec save is passed they take half damage, DC is determined by your spellcasting ability.
