The Cosmic Entropy Leviathan: strike it while it is stuck.

What it is

A void-dragon forty-five metres long, with a galaxy turning in its chest and six neon tentacles. It drifts over the land of the strange universes, and where it passes the world runs down.

Where and when it comes

• Only in strange universes at tier eight and up, on open ground.
• It drifts in 70 to 85 metres from someone on the ground.
• After one is slain, another cannot come for about 50 minutes. The Codex hint is "The end of everything, drifting".

How the fight works

1. Lashing. Two tentacles lash down on a ringed spot. They stay stuck for a moment, and its core is open. Strike it then.
2. Orbs. Orbs of nothing drift slowly toward you and eat the ground where they land. Move out of their path.
3. Entropy field. Now and then it lets the world run down round it. In this field you lose health every second, until a blow to its head or core breaks it out.
4. Calling strangers. Halfway down its health, it calls strangers out of the dark.

Tips

• Watch the ringed spot. The tentacles land there.
• Keep a path out of the entropy field and do not linger in it.
• Be ready for the strangers it calls.
