Horse Girl

You've always had an uncanny connection with horses and other equine creatures. Through a mysterious bond, you've gained the ability to temporarily assume the majestic form of a unicorn. You gain the following benefits:

• You know the Find Steed spell and can cast it three times per long rest without consuming a spell slot. You may only summon a Pony when casting the spell this way.
• While you are missing half or more of your hit points, as an action, you can magically transform into a Unicorn, as described in the Monster Manual, for 1 hour. This transformation ends early if you are reduced to 0 hit points or if you use a bonus action to revert to your normal form.
• While in the form of a Unicorn, you may not take legendary or lair actions. However, you may cast Bless at will as a bonus action. Additionally, every time you heal an ally, you heal yourself the same amount.
• When you revert to your normal form, the taxing nature of this transformation leaves you physically and mentally drained. You take 3 levels of exhaustion, and 1d10 force damage per level of exhaustion you have. This damage is halved if you used a bonus action to revert forms. Additionally, all spells slots above 1st level are consumed. Starting at 12th level, the level of exhaustion taken is reduced to 2 and no spell slots are consumed.
