Ethereal Ark is an overhaul mod that supports crossplatform and introduces various abilities, creatures, armors, and bosses.

Ethereal Abilities: Unleash the hidden potential of your tamed dinosaurs with powerful abilities like dashing, teleportation, lava erupting from the ground, ice spikes that freeze enemies, toxic gas that induces torpor, lightning strikes, and more. There are over 33 unique live abilities.

Tiered Progression: Work your way through multiple creature tiers. Wisps (bright white glow) are the weakest, Shades (purple color) are stronger, followed by a wide range of Elementals. The mod currently includes over 13 tiers (not including the evolution tiers that has over 10 tiers!), with more planned.

Pygmy Evolution System: Introduces a new progression path through Pygmies. Start by taming a basic pygmy like a regular creature, then evolve it into various support or combat-focused forms across 11 total evolutions/tiers.
Guardian Path: A special evolution path for pygmies that comes with its own custom mission system.

Cursed Dinosaurs: Some tamed creatures can become cursed, gaining dark powers and new abilities. Not all dinos can be cursed, and while wild cursed dinos can’t be tamed, they may hint at which of your tames are eligible.

Mini-Bosses and Bosses: Prepare to challenge tough custom mini-bosses and full-scale bosses with new mechanics and abilities (unique to themselves) that test both your gear and strategy.

Special ability item system: Craft or loot special items from ethereal creatures to gain access to their powers and use them yourself.

Armor System: Features two types of armor:

Randomized armor that provides passive stat bonuses.
Elemental armor that grants special effects based on the element, like fire burns or storm dashes. Mix and match to suit your playstyle. If your lucky even elemental armor can have passive stat bonuses!

Spawn System Compatibility: Automatically adds missing dinos to any map and replaces vanilla creatures with ethereal versions, making the mod fully playable on any map.

Built for Challenge: This mod is designed to be tough. You can make it a little easier for you through ini settings.

Recommended Level: 150
Helpful Tools: Compatible with Awesome spyglass or super spyglass plus for better tips and guidance. Some spy glass mods won't show you the real requirements like Nanoh's spyglass mod.
