The Dino one shots jelly fish is immune to their dismount and immune to eel stun. The archelon is also very slow but has rlly good stamina and health, its damage is mid. But it gets a buff when it is to kill a jelly fish similar to when you kill bugs on a megatherium. All and all this is honestly a really good tame to have especially because it’s saddle gives you infinite oxygen while riding it or close to it.
