Talaphor’s Transformation

The sword’s essence flows into you, granting you great endurance and martial prowess at the cost of your magical abilities. Until the spell ends, you can’t cast spells, and you gain the following benefits:

• You gain 50 temporary hit points. If any of these remain when the spell ends, they are lost.
• You have advantage on attack rolls that you make with this weapon.
• When you hit a target with a weapon attack, that target takes an extra 2d12 force damage.
• You are immune to fire and poison damage.
• Wings of shadow appear on your back, giving you a flying speed of 40 feet.
• You have a +2 bonus to AC. 

Immediately after the spell ends, you must succeed on a DC 15 Constitution saving throw or suffer one level of exhaustion.
