Overall Rating: Blue. This means that
tasha’s otherworldly guise is a great spell and you should strongly consider this spell for your character.
Overall Notes: Bonus action to gain +2 to AC, damage immunities, and flight make this a solid defensive spell. Even though the spell grants the ability to make attacks with spellcasting modifier and allows you to attack twice, you will rarely use these features as a unless your a martial spellcaster.
