Sage Advice

For the hat of disguise, how do I set the spell save DC for disguise self? Does the wearer have to be a caster?

Use your spellcasting ability modifier to set the DC. If you don’t have a spellcasting ability, use your proficiency bonus to set it (see the rule on page 141 of the DMG, under “Spells”).

Disguise Self

PHB p233

1st-level illusion

Casting Time: 1 action

Range: Self

Components: V, S

Duration: 1 hour

You make yourself—including your clothing, armor, weapons, and other belongings on your person—look different until the spell ends or until you use your action to dismiss it. You can seem 1 foot shorter or taller and can appear thin, fat, or in between. You can't change your body type, 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 hat to your outfit, objects pass through the hat, and anyone who touches it would feel nothing or would feel your head and hair. If you use this spell to appear thinner than you are, the hand of someone who reaches out to touch you would bump into you while it was seemingly still in midair.

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

Further Notes

The disguise self spell does not change your voice. You can make a Performance check to attempt impersonation.
