| Mechanism 1 ▼ | Mechanism 2 ▼ |
| Mechanism 3 ▼ | Mechanism 4 ▼ |
The first mechanism is the one the quest will prompt you to activate and lead you to find three other mechanisms!
| How to Activate Mechanism 2 | |
|---|---|
| 1 | Head into the corridor near the first mechanism. |
| 2 | Turn right to see the second mechanism, the gate, and the controller that opens it. Defeat the enemy guarding the gate. |
| 3 | Open the gate that leads to the rotating circular bridge like the one in the Silvermane Guard Restricted Zone. |
| 4 | From the gate, head straight then right. The second mechanism is there, guarded by an Everwinter Shadewalker. |
| 5 | Defeat the enemy and activate the mechanism! This will open the second lock on the main door in the area. |
| How to Activate Mechanism 3 | |
|---|---|
| 1 | The next Mechanism Energy Hub is near the second mechanism. However, it is locked behind a door with the only way to open it is the controller on the other side of the gate. |
| 2 | To get there, you must operate the controller right beside the Space Anchor. |
| 3 | This controller can turn the circular bridge either Clockwise or Counter-Clockwise. Turn it Counter-Clockwise. |
| 4 | Once the bridge has turned, this will open the path from the right of the bridge. That path has the first Cavern of Corrosion we encounter! |
| 5 | Defeat the Incineration Shadewalker guarding the mechanism. |
| 6 | Activate the mechanism to unlock another part of the gate! |
| How to Activate Mechanism 4 | |
|---|---|
| 1 | From the right of the mechanism, unlock the door to open the connecting corridors between the two. |
| 2 | Operate the bridge controller again and turn it counter-clockwise. |
| 3 | Head back to the path near the Cavern of Corrosion and go to the last mechanism. |
| 4 | Defeat the Everwinter Shadewalker guarding the mechanism. |
| 5 | Activate the mechanism to finally open the gate! |
| 6 | You can get back to the area by going left of the mechanism and opening the gate there! |

You must use March 7th's Skill to steadily shield your allies from the healer to the damage dealers or toughness breakers. This is due to Cocolia's various heavy DMG AoE attacks.
You must also bring a healer with you to keep your team alive for as long as possible.
Cocolia has a high DMG AoE attack that she must charge up for a few turns first before executing. Break her toughness during this time to avoid tanking this attack!
Cocolia will produce two large ice lances that can periodically unleash an AoE attack. To avoid that, you must break its toughness using either Fire or Lightning, then destroy it!
