Ectoplasm Press for the Collector Guide

Craft the Revelwood Bone Key, enter the Revelwood Hollow Halls, and defeat the Hollow Cyclops to obtain its head. Return to the Collector to craft an Ectoplasm Press, then place it at your base.

Talk to the Collector to craft a Revelwood Bone Key. Prepare 5 Ectoplasm Gems and 20 Bones.

Each Ectoplasm Gem requires 1 Water, 1 Bonemeal, and 2 Ectoplasm Fragments at the Collector. The crafting requirements also list the Collector and a Sheltered Bed.

The entrance lies northwest of the Ancient Spire in Revelwood. One route is to glide toward the marked location from the spire, then continue on foot.

Use the Revelwood Bone Key at the large entrance door. Inside, use the platform ahead to enter the Hollow Halls.

The first barrier opens after you collect 2 orbs. In the room on the left, grapple to the anchor above the doorway and take the orb on the upper platform.

Return to the corridor and enter the room to the right of the barrier. Grapple to the upper platform, then use the next anchor to cross. Jump to the platform holding the other orb.

The next large door is opened by switches along the left and right paths.

Follow the left path through the fireball hallway. Time jumps between the rows, look up for the anchor, and use the grappling hook and chain-link wall to climb. One route continues with a double jump and a grapple across the platforms, then another anchor to the upper platform.

Go through the doorway and activate the button at the end of the long hallway.

On the right path, follow the corridor to the stairs. Defeat the 10 marked enemies at the barrier, then continue to the second button. Return to the main door after activating both switches.

Beyond the main door, activate the respawn point and repair equipment at the nearby anvil.

The next barrier requires 8 orbs. Look for 4 in the open area and 4 in the caves and tunnels below, on either side. Use the grappling anchors to move between lower platforms.

Further ahead, slide down the slope while avoiding the glowing green patches. Before the bottom, use the anchor overhead to climb above the spider nest.

From the platform, double jump and glide toward the chain-link wall, then climb it. Continue through the enemy-filled corridor to the long stairs. Climb either side and grapple up into the boss room.

Defeat the Hollow Cyclops in the boss room. Smaller enemies also appear during the battle; area attacks can help deal with the group. After the boss falls, loot its body for the Hollow Cyclops Head.

Return to the Collector at your base and gather the materials below to craft the Ectoplasm Press. The crafting requirements also list the Collector and a Sheltered Bed.

Place the crafted Ectoplasm Press at your base to complete Ectoplasm Press for the Collector.
