Hollow Rock

Two Hollow Rocks can be found near the gate to the Ember Ward where Stonehead stands guard—one inside the ward and one outside. Interacting with a Hollow Rock grants for 10 minutes, disguising you as a rock and allowing you to pass through the gate without Stonehead stopping you. He'll simply remark:

Donning a Hollow Rock also allows you to reach the Chewed Light Shard next to Stonehead and pick up its quest, Snacks for Stonehead.

• The Hollow Rock outside of the ward will not respawn as long as you're on Snacks for Stonehead. Additionally, this quest causes Stonehead to throw you out of the ward instead of into it. To get back in without having to take a longer way around, simply drop the quest, use the now-respawned Hollow Rock, and pick the quest up again on your way in.
