Overview
The Leedsichthys is a massive aquatic carnivore found in ocean biomes. It excels at damaging structures, making it a niche siege mount in underwater bases. It can be airlifted by Quetzal or Karkinos for fast deployment.
Due to its size and role, it is primarily used in PvP scenarios to breach enemy underwater fortifications.

Conversely, it is fully immune to mining drill harvest damage, taking -100% damage from that source. Melee attacks with impact effects and small ranged turrets are only half as effective.
The head is a weak point, taking 1.5× damage. Target the head for faster knockouts or kills.
