When attacking, use Basilosaurus whales, they cannot be grabbed, be aware that once low health, the squid will flee and emit ink, and debuff you by making all nearby creatures aggro you. I almost lost a 265 basilosaurus to 4 dunkleos and 10 megalos that boxes me into a star formation.
Use a Mosa to tame this beast. Let the Mosa get grabbed wait a couple seconds get off feed it black pearls. Have your mosa on follow lowest, swim a bit away from the Tuso after feeding it, when the Tuso lets go the Mosa will swim to you. Repeat until Tuso it tamed. Super easy!
The Tusoteuthis is a massive, aggressive squid found in the depths of the oceans. In battle, the Tusoteuthis can grab its prey and knock it unconcious, siphoning its blood to gain health. Once tamed, the ink from a Tusoteuthis can be used as a constant Oil source. Some survivors choose to hunt the Tusoteuthis for its Oil.
