Lost Ceratosaurus
Variant
Overview
The Lost Ceratosaurus is a carnivorous variant creature with a unique venom-based attack mechanic. It can be carried by Tusoteuthis for aerial transport and ambush tactics. This pairing enables rapid deployment into combat zones or remote areas for efficient hunting and node control.
It excels in offensive roles where its high-damage special attacks and structural damage capabilities are utilized. Players tame it primarily for its ability to exploit weaknesses in enemy defenses and deal significant melee damage.
