How to find the Forest Fortress in Tunic

Beneath the Eastern Vault guide

At the bottom of these ladders,destroy all of the crates with your swordand look for a crack in the wall. Head through this crack to enter an underground cave. Wade into the water and follow it right to find another passage. Walk down this corridor and through more water to find a chamber lit with a dim blue light. Kill the Spyrite and other enemies in here and then head through the doorway on the right side of the room.

With that power block activated, head back into the Forest Fortress and head up the stairs in this main hallway. Kill the Custodians at the top and then activate two more power blocks to open the sealed golden door at the end of corridor. Head into the next chamber and rest at the save point at the end of the path.

When you’re ready for a boss fight, head up the stairs until you find theSiege Engine. This is the boss of the Forest Fortress dungeon and it’s an absolute behemoth, so be prepared for a tough fight ahead. If you want more help with this fight, check out our Siege Engine boss fight guide.

After defeating the Siege Engine, take the small device that drops on the floor and head back down the steps. Use the device in the centre of the strange metal hexagon that’s positioned just above the save point to open a pillar that holds the red key. Simply grab the red key to add it to your inventory and complete the Forest Fortress dungeon. There’s nothing left to do here, so head back to the Overworld when you’re ready and take the red key to the Sealed Temple.
