Archelon [PvE Cross]

Archelon is a herbivorus giant sea turtle that works as a tanky underwater transport and a bio toxin farmer. It can slowly walk on land, but the babies must grow in water (the babies eat a lot!).
 
Its saddle seats a rider and 4 passengers, and anyone near an Archelon wearing the saddle gets a buff that refills their oxygen. It can swim straight up and down on command, so it's a good way to move a group around the ocean.

It's immune to stuns and to jellyfish stings and deals 10x damage to jellyfish, so it clears them out quickly. After it kills one, it gets a buff that boosts its Bio Toxin harvesting and reduces the damage it takes for a short time.
 
It also passively produces Archelon Algae, which is used for taming wild herbivores (almost as effective as kibble). It produces it more quickly while swimming, so a swimming Archelon is a steady supply.
 
It's slow, not much of a fighter, and weak to explosives, so it's best for transport and farming.

All Archelons are 100% imprinted and come with saddles and levels available.
