You transform into a shadowy form, becoming intangible and invulnerable for the duration. In this form, you gain the following benefits:

• You gain immunity to necrotic damage and poison damage, and resistance to all other damage types for the duration.
• You can move through other creatures and objects as if they were difficult terrain. You take 5 (1d10) force damage if you end your turn inside an object or creature. If your turn ends inside a creature, they take the same 1d10 force damage.
• Your speed increases by 10 feet, and you can move without provoking opportunity attacks.
• You can pass through openings as small as 1/4 inch in diameter without squeezing.

While in Wraith Form, you cannot attack, cast spells, or interact with objects. You can end the spell early by using an action to dismiss it.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the duration increases by 1 minute for each slot level above 3rd.
