Find where you died
Use /dc for death-coordinate information. Note the coordinates and return to that location.
Recover your items in time
Graves last 10 minutes. When a grave expires, its contents drop onto the ground. Reach the location promptly rather than relying on the grave to hold items indefinitely.
Do not assume a grave is private
Graves are not documented as private or theft-proof. Other players may be able to collect their contents, so do not treat a grave as guaranteed item protection.
Travel back carefully
Use your base teleport or a player teleport request when it helps you reach the area. A player request still needs acceptance and its countdown.
/back returns to the previous saved teleport location; it does not return you to your death location. Use /dc for the death location.
