Feeding Grounds stays sealed until you smash three matching graves in Stones of Remembrance. The door does not take a key. It answers the same glowing mark that sits on three tombstones in the cemetery around it.
Quick answer: Hit every gravestone marked with a glowing orange or yellow symbol that matches the chapel door. The door opens. Drop through the center floor inside, use the switch in the pit, then open the sarcophagus for the Myriad Stone.
Unlock Feeding Grounds with three gravestones
The locked entrance sits in the northeast of Stones of Remembrance, in the Northern Graveyard around a ruined chapel. Yellow flowers cover the tombs and the path in. Walk the cemetery until you can see the sealed door. The symbol on that door is the only mark that matters.

Roam the ruins and headstones near that door. Three graves carry a bright orange or yellow glyph, and they are the ones you want. Ordinary stones do nothing. Strike each marked grave until it breaks. After the third one falls, the chapel door opens and the dungeon is named Feeding Grounds.

If the door is still shut, one of the three marked stones is still standing. Keep circling the same cemetery. The glow is easy to miss in the flowers, but it matches the door exactly, so you are not guessing which graves count.

Take the stairs down once the door is open. The first room is a short fight and a trap. Clear it on your terms, then drop on purpose. The rest of the route is a pit, a switch, one heavier enemy, and a breakable wall.

Wooden wall and the sarcophagus

Myriad Stone reward
The dungeon pays out one Tarstone, the Myriad Stone. Open your Tarstones menu and look for that name. The stone is the upgrade for the Forgotten Crossbow, so the run is done only after the item is sitting in that list.
| Action | Confirmation |
|---|---|
| Third marked gravestone breaks | The Feeding Grounds door stands open |
| Switch in the pit is used | “A gate has lifted” appears |
| Sarcophagus is opened | Myriad Stone is listed under Tarstones |
A still-locked door means a marked grave is left. A gate that never moves means the pit switch was not used. Anything short of Myriad Stone in the Tarstones menu means the sarcophagus is still closed.
