Phoenix spirit

You have mastered fire based magic and can induce a powerful and very dangerous form in which the power of the phoenix flows through your veins.

• You can use a bonus action to enter your phoenix form and it lasts 10 minutes. You can do this once per long rest.
• In your phoenix form all weapon attacks and fire magic attacks do an extra 1d8 radiant damage.
• The phoenix spirit causes your entire body to be surrounded in a radiant flame thus causing any creature that hits you with an attack to make a DC (11+ your spellcasting modifier) constitution saving throw. On a failed save they take 1d10 radiant damage and half as much on a successful one.
• This form quite powerful. However, this power is also quite dangerous. Whenever you are attacked you have to make a DC 13 wisdom saving throw. If you fail then you are forced to cast a 3rd level fireball spell to a random point chosen by the DM.
• You also gain the ability to rise from the ashes. This ability activates whenever your hit points reach 0. If your hit points hit zero while in your phoenix form then you instantly burn up into a pile of ash. You then rise from the ashes with half of your maximum hit points. However rising from the ashes automatically forces you out of your phoenix form.
• When you exit the phoenix form you are burnt out which means that gain 1st level exhaustion.
• Your phoenix form gives you an immunity to fire damage and a weakness to cold damage.
• You can harness the power of the phoenix to fly with a flight speed of 50ft. However When you are in flight you can no longer cause radiant damage to those who attack you.
