Where to get Infused Ooze
The dependable Grounded 2 source for Infused Ooze is the O.G.R.R. Toe-biter Leviathan inside the Abyss. Advance the Into the Abyss story until it leads through the Monitoring Station laboratory and into the creature's flooded arena.
Killing the Leviathan places the Infused Ooze on the floor. It does not move directly into a full inventory, so clear at least one slot before the last hit and inspect the ground before leaving. Treat that pickup as the final step of the fight.
| Step | What to do | Why it matters |
|---|---|---|
| Reach the Abyss | Follow the current pond story and enter the deep underwater region | The ooze source does not appear in the normal park map |
| Enter the Monitoring Station route | Continue through the laboratory objectives | The route leads to the Leviathan arena |
| Defeat the Leviathan | Use underwater weapons and arena cover | The boss provides the Infused Ooze drop |
| Collect the floor drop | Keep one inventory slot open and check the corpse area | Leaving the item behind can block the upgrade |
Prepare before entering the arena
Finish the diving progression first and enter with the complete underwater kit required by the Abyss route. Repair the gear before the descent because returning to the surface turns a short preparation mistake into a long trip.
Bring this combat loadout:
- A Harpoon Gun with a large reserve of harpoons, or a strong underwater spear and shield.
- Several healing items that can be used while submerged.
- Buffs suited to the weapon and the Leviathan's gas pressure.
- One free inventory slot reserved for Infused Ooze.
- A manual save before entering the final arena.
The ranged setup gives the cleanest control. The entrance and solid arena geometry create distance while firing harpoons. A spear setup also works, although it demands tighter parries and more careful positioning.
Beat the Leviathan without losing control
The arena poles, corners, and raised edges are practical cover. Keep one solid object between the character and the Leviathan whenever healing, waiting for a status to clear, or dealing with its smaller juveniles.
Use a patient loop:
- Pull the Leviathan toward a pole or corner instead of meeting it in open water.
- Deal a short burst of damage, then return behind cover before the counterattack.
- Stop attacking when several juveniles are active and clear them or wait for their short lifespan to end.
- Move early when gas pressure closes the current position.
- Repeat until the Leviathan falls, then collect the ooze immediately.
Greedy attacks create most of the danger. Underwater movement limits fast corrections, while juveniles and gas can turn one missed defense into a full status chain. Keeping the fight slow protects the run and the final drop.
Use Infused Ooze for the Tier 4 axe
Infused Ooze is the progression material for upgrading the axe side of the Omni-Tool to Tier 4. The upgrade opens the next chopping tier needed by late-game materials in the Into the Abyss progression.
This item comes from a boss drop, not a Workbench recipe. Once it is safely in the inventory, return to the Omni-Tool upgrade interface and complete the axe upgrade.
Protect the first drop
The Leviathan encounter is the only dependable acquisition route in the current update. Plan around one pickup from the first victory and collect it before leaving the room.
Before the final hit, confirm the inventory slot, save the game, and keep the arena in view. After the kill, search the floor around the body and collect Infused Ooze before interacting with another objective.
