Venturing to the scarlet rot-infested lands of Caelid, located east of Limgrave, is no easy feat for new Elden Ring players.

Underneath these ruins is a teleporter trapped-chest which sends you to a cavern in Caelid, the Sellia Crystal Tunnel, which is full of diggers and prawn miners.

Don’t worry if you can’t fight these enemies yet; simply turn
