THE LEVIATHAN MOD
This mod adds the Leviathan. A boss that spawns in deep cold ocean when it thunders. It hunts fish, dolphins, squid and, of course, players.
The Leviathan has 104 health and when killed, drops its scale that can be crafted into Leviathan Boots. The Leviathan Boots give dolphin grace effect for 10 seconds.
Leviathan fossils can be found on the bottom of the deep cold ocean.
You can also use the OG resourcepack that gives the Leviathan its concept look.
