Requirements

• Must have beaten the Astra Malorum Main Quest
• Playing on any tier of Cursed
• Playing on Astra Malorum
• Must be Round 20 or above
• Dead Wire
• Tesla Storm

Using the Lightning Strike and Haste is recommended to ensure the zombie gets stunned and you can trigger dead wire more often. I don't put on any major augments on your field upgrade to avoid dealing extra damage to the zombie.

How to Unlock

On Round 20 and above, a zombie with a Lightning Rod lodged in its body will spawn which you'll need to trigger Dead Wire on and then activate Tesla Storm and touch the zombie while it's affected by Dead Wire next to one of three lights around the map to turn them on.

The zombie needs to be affected by both effects to charge each light. Make sure to use a low-rarity weapon to avoid accidentally killing the zombie. The rod zombie also cannot despawn, so if you spot him, you can run very far to have all other zombies respawn so you can safely kill them while the rod zombie runs across the map to you.

There is no order in which you need to turn these lights on. Below are the three light locations:

Once all three lights have been turned on, you will hear Mister Peeks laugh and the relic trial portal will spawn outside the Observatory Dome in Stargazer's Courtyard for you to enter. This relic's trial is: Zombies can only be damaged by electric damage.

I recommend putting Dead Wire on your weapon to make this trial much easier as all your bullets will deal electric damage.
