Nasgard Jellyfish
The oceans of ARK: Survival Ascended have always been dangerous, but the Nasgard Jellyfish takes underwater terror to an entirely new level. This creature add-on introduces a drifting horror that has wandered far beyond the waters of its home map, and it is only a small glimpse of what waits beneath the surface. If you are ready to expand your creature roster with something that stings harder than anything vanilla has to offer, this mod deserves a place in your load order.
What Is the Nasgard Jellyfish?
The Nasgard Jellyfish is a custom creature mod that adds three distinct variants of a menacing jellyfish to the game. All three share spawns with the vanilla Cnidaria in the Wildlife 1 spawn category, which means you will encounter them naturally while exploring the open ocean rather than hunting for a rare custom spawn point. The mod is designed to feel like a natural extension of the ARK ecosystem, and it fits seamlessly alongside other creature packs.
Each variant scales differently in power and size, giving survivors a reason to seek out the more dangerous versions for tougher tames and better rewards.
The Three Nasgard Jellyfish Variants
Normal Nasgard Jellyfish
The baseline version behaves much like an oversized, aggressive Cnidaria. It is the easiest of the three to handle and serves as a solid introduction to the mod's mechanics. Use the cheat command admincheat summon NasgardJelly_Character_BP to spawn one instantly on your server or in single player.
Aberrant Nasgard Jellyfish
The Aberrant variant deals 1.06x damage and is twice the size of the normal version. Its larger hitbox makes it a genuine threat in tight underwater caves, and its boosted damage output punishes careless swimmers. Spawn it with admincheat summon NasgardJelly_Character_BP_Aberrant.
XY Nasgard Jellyfish
The XY variant is the apex of the trio, boasting 2x damage and 2x size. This is the creature you bring friends for. It hits like a truck and dominates any stretch of ocean it drifts through. Summon it with admincheat summon NasgardJelly_Character_BP_XY.
How to Install Nasgard Jellyfish for ARK: Survival Ascended
Installing this add-on is straightforward for anyone familiar with ARK modding. The mod is compatible with current ARK: Survival Ascended versions, and the developer actively maintains it alongside ongoing updates. Before you download Nasgard Jellyfish, make sure your game client is updated to a recent build, since older versions may not recognize the custom spawn entries.
- Subscribe to the mod through the in-game mod browser or your preferred add-on catalog.
- Add it to your server's active mod list and restart the server.
- Verify the mod loaded correctly by checking the spawn commands in the admin console.
- Test the creature in single player before rolling it out to a live cluster.
If you prefer a smoother setup, the foxygame.net launcher handles the entire process with a single click, pulling Nasgard Jellyfish directly into your mod library and keeping it updated automatically whenever the developer pushes a patch. That convenience matters when a mod receives frequent balance tweaks.
Compatibility and Future Content
This add-on plays nicely with most creature and spawn-overhaul mods because it hooks into the existing Cnidaria spawn entries rather than creating isolated spawn zones. That design choice keeps your ocean populated without breaking other wildlife mods. The developer has confirmed that a Chibi is on the way, along with custom resources called Nasgard Black Pearl and Nasgard Bio-Toxin, plus a full dino dossier. A teaser also hints that the Nasgard map is coming soon, meaning this jellyfish is just the opening act.
For server owners running multiple creature mods, the shared spawn approach is a major plus. You will not need to rebuild your spawn configs from scratch, and the variants will appear naturally in the same waters where Cnidaria already thrive.
Final Thoughts
The Nasgard Jellyfish is a compact, well-executed creature mod that adds real danger to ARK: Survival Ascended's oceans without bloating your load order. Three variants, escalating difficulty, and a clear roadmap of future content make it an easy recommendation for players who want more reasons to fear the deep. Download it, spawn a few XY variants, and see how long your tribe lasts against the tide.
