Vampire, Stage 3 (Improved Shapechanger)

Requires you to have taken Shapechanger.
When you use your Shapechanger ability, you may also take on the form of a dire wolf. While in the dire wolf form you gain the following features:
• Your movement speed changes to 50 feet.
• If you have sunlight hypersensitivity, it is reduced to sunlight sensitivity.
While in the dire wolf form, you cannot speak. Any object you are holding or armor you are wearing merges into your wolf form or immediately drops to the ground. The Gm may decide if they feel the object cannot merge. If you become unconscious in your dire wolf form, you revert back to your vampiric form. Additionally, you gain the ability to use Fanged Bite while in animal form. The piercing damage for your Fanged Bite changes based on your form. While in bat form, you deal 1 piercing damage, and while in dire wolf form you, deal 2d6 piercing damage. While in mist form, you may cast the spell fog cloud once without expending a spell slot and without using verbal, somatic, or material components. You regain the ability to cast this spell when you finish a long rest.
