[Nauquan]

The first time, I magic dueled it to death with a bunch of Astral-1 lizards - some luck involved.

The second time it ran into my army, and got quite a few afflictions - less tenticles was one. I had foul vapors up and a litle poison helped. I don't remember what killed him in the end but it may have been an underwater Sleeper with an Etheral Crossbow.
