Burning Passion

After you were taken away by the lovely Heatherly she gave you her dark passionate blessing. Now a dark purple tattoo of a heart with a devil's tail marks your body. A sign of possession and passion. While marked this way you gain the following benefits.

• While flirting you gain a bonus 1d8 to the check.
  
  
• Your hair always looks immaculate. Eyes and nails on fleek.
   
• As an action you can imbue yourself with her power for 10 minutes and gain the following:
  - Dark purple wings of flame manifest giving you a flying speed of 60ft.
  - You are immune to fire damage and have resistance to cold damage. Additionally fire damage you deal ignores resistance to fire damage and treats immunity as resistance. Though for monster this only works up to CR 15.
  - Any creature that moves within 5 feet of you for the first time on a turn or ends its turn there takes 1d10 fire damage.
  - You can use your action to create a line of dark purple fire 30 feet long, 15 feet high, and 5 feet wide extending from you in a direction you choose. Each creature in the line must make a Dexterity saving throw(Your Spell save DC). A creature takes 5d8 fire damage on a failed save, or half as much damage on a successful one.
  - Once the 10 minutes are up you drop to half your current hit points and suffer 2 levels of exhaustion. 

Her love is not without cost, in order to keep this power going you must visit her to charge it. The imbuement can only be done three times before you must visit her once more.
