The Brine Warden: fight it while it is up.

What it is

A pale, pickled eel that lives in a lake of brine on the open sea floor, with a shore of salt and wrecks pickled on its bottom. It is based on real brine pools on the floor of the Gulf of Mexico, with shores, waves and animals that swam in and were pickled.

Where and when it comes

• Far down on the open sea floor, at least 40 metres under the waves, in the Wide Blue or the Hadal Rift.
• Its lake sits on a flat stretch of floor 40 to 55 metres from you.
• After one is slain, another cannot come for about 30 minutes. The Codex hint is "A lake at the bottom of the sea".

Why you cannot dive in

The brine is so salty you float on it like a floor. You cannot swim down into it. The Warden circles under the face of the lake, and swimming low over the lake brings it up.

How the fight works

1. Surging. It rises out of the brine when you swim low over the lake.
2. Gripping. It takes hold and drags you under, where nothing floats you and the salt pickles you.
3. Breaking free. Strike its head hard to break its grip.
4. Sinking. Under the brine nothing can touch it. It is only open to blows while it is up out of the brine.

Tips

• Do not hover over the lake. Stay out of its ring and keep moving.
• Hit its head when it surfaces. That is the blow that breaks its grip.
• Bring a way to get back up, as the brine pulls you down.
