Disguise Other

Astaevian Spell

You make a willing target medium or smaller creature -- including their clothing, armor, weapons, and other belongings on their persons -- look different until the spell ends or until you use your action to dismiss it. You can cause this creature to seem up to a foot shorter or taller and they can appear thinner, fatter, or of any other build. You can't change your bodily configuration, so you must adopt a form that has the same basic arrangement of limbs. Otherwise, the extent of the illusion is up to you.

The changes wrought by this spell fail to hold up to physical inspection. For example, if you use this spell to add a cloak to a creature's repertoire, objects pass through the cloak normally, and anyone who touches it would feel nothing or would press against that creature's back. If you use this spell to make a creature appear thinner, the hand of someone who reaches out to touch them would contact them, while  all others would see their hand still in midair.

To discern that you are disguised, a creature can use its action to inspect that creature's appearance and must succeed on an Intelligence (Investigation) check against your spell save DC.
