6th-Level Transmutation
Casting Time: 1 action
Range: Self
Components: VSM (a few hairs from a bull)
Duration: (C) 10 minutes

As in Xanathar's Guide to Everything except the failed save now gives a level of fatigue instead of exhaustion and the following has been added:

- You have proficiency with all armor, shields, simple weapons, and martial weapons. When you cast this spell, or as a bonus action on subsequent turns, you can don or doff any armor or shield you are touching or wearing as a bonus action. When the spell ends, you can choose to automatically doff any armor or shield you are wearing.

- All your weapon attacks are magical, and when you make a weapon attack, you can use your spellcasting ability modifier, instead of Strength or Dexterity, for the attack and damage rolls.

At Higher Levels. When you cast this spell using a spell slot of 8th level, the duration is concentration, up to 1 hour.
