You step into a stone object or surface large enough to fully contain your body, melding yourself and all the
Equipment you carry with the stone for the
Duration. Using your
Movement, you step into the stone at a point you can touch. Nothing of your presence remains visible or otherwise detectable by nonmagical
Senses.
While merged with the stone, you can't see what occurs outside it, and any
Wisdom (Perception) checks you make to hear
Sounds outside it are made with
disadvantage. You remain aware of the
Passage of time and can cast
Spells on yourself while merged in the stone. You can use your
Movement to leave the stone where you entered it, which ends the spell. You otherwise can't move.
Minor physical damage to the stone doesn't harm you, but its partial
Destruction or a change in its shape (to the extent that you no longer fit within it) expels you and deals 6d6
bludgeoning damage to you. The stone's complete
Destruction (or
Transmutation into a different substance) expels you and deals 50 bludgeoning damage to you. If expelled, you fall
prone in an unoccupied space closest to where you first entered.
