Once per day, when the command word is given and this fine ebony comb is dropped to the ground, it transforms into a wall of thorns, as the spell, shaped to the desire of its owner.

If the wall is destroyed, the comb immediately reverts back to its normal form and cannot be used again for a week. Otherwise, it reverts back to comb form after an hour or when its owner gives a second command word.

Notes: If the wall is destroyed, the comb immediately reverts back to its normal form and cannot be used again for a week.
