Elden Ring: Shadow of the Erdtree introduces a whole new group of painfully difficult bosses and dungeons for Tanrished to explore. Very early in the DLC, players will face several extremely daunting challenges, culminating with the second in a pair of legacy dungeons in Gravesite Plain: Castle Ensis.

This guide will help players prepare for their journey, providing a complete guide to the Castle Ensis legacy dungeon in Shadow of the Erdtree.
