The Jellyfish is not the strongest ship in the game, but is extremely important to progression in the game. There is an event that does not show up until you get the Jellyfish which rewards a pile of 4* materials, making it extremely important, especially at 39 to source these materials you wouldn't be able to get otherwise.
There are three ways to get Jellyfish blueprints. The first and easiest is from Epic Armada Chests. It shows up in these chests once you hit Ops 36, and from Ops 38 there is a chance, albeit tiny, to get a full pull from these chests.
The second way comes in a 3* spend event SLB. The rewards for this are based on server age, so each server has different rewards, sometimes awarding several full Jellyfish BP drops in the top places, sometimes only have first place giving a full drop. The lower places get partial pulls of blueprints.
The last way is if your alliance has 3* territory. These territories have the ISS Jellyfish Constructor as a a service. Level 39 players will be able to purchase blueprints once a week from this.
| Iso Emulsion Cost | Blueprints |
|---|---|
| 6,500 | 1 |
| 45,000 | 5 |
| 500,000 | 15 |
As territory research is so strong, until you're deep in the tree it will be hard to choose Jelly BPs over research, but that is a decision that you need to personally make.
You must kill 50 ships with the Jellyfish in one of three systems:
| Ops Level | Uncommon 4* Explorer Parts | Common Explorer Parts | Uncommon 4* Gas | Common 4* Gas | Uncommon 4* Ore | Common 4* Ore |
|---|---|---|---|---|---|---|
| All | 4855 | 6115 | 2195 | 810 | 1190 | 435 |
+50% to the ability of ISS Jellyfish against hostiles.
