The Oasisaur is a walking desert island — a passive tame that, once tamed, carries a rejuvenating pool on its back and can bring a fallen tame back from the dead. The tame is a short escort mission, not a feeding session.
It is the only flying base in the game that resurrects your team, and getting it uses up a creature you probably like.
The numbers
| Stat | Value |
|---|---|
| Taming type | Passive (mount & inject Death Essence) |
| Health | 20,000 |
| Food | 8,800 |
| Weight | 2,500 |
| Melee Damage | 0 |
| Torpor | 10,000 |
| Preferred food | None — it needs a Death Essence, not kibble |
| Found on | Scorched Earth, Astraeos |
The base stats above are Dododex-reported and approximate — community-sourced, not officially verified. It takes no kibble at all: the tame runs on a Death Essence and a rifle, and what you get back is a floating base with a healing pool on it.
The method, in one sentence
Climb onto its back, put a Death Essence in the oasis inventory, then hold off three waves of Vultures while the spawned baby clone survives and the taming bar fills.
That is the whole tame. Everything hard about it is in the execution.
Step by step
- Gather the two things you need: the Death Essence of a deceased creature and a weapon. A Fabricated Sniper Rifle or a Longneck Rifle with ranged ammo is the recommended setup — you will be shooting vultures out of the air, not hitting one big target.
- Climb onto the Oasisaur’s back. You can land on it with a flying creature or use Grappling Hooks. You have to be riding it for the mini-game to start.
- Put the Death Essence in the oasis inventory. A baby clone of the resurrected creature spawns in the oasis, and three bars appear over it: the green bar is the baby’s health, the white bar shows how many enemies you still have to kill for the current wave, and the orange bar is the taming progress itself.
- Kill the vultures, wave by wave. Vultures spawn around the Oasisaur and home in on the baby. Each wave comes at a higher level — level 31 for the first wave, level 61 for the second, and level 121 for the third.
- Protect the baby. If it takes too much damage while the mini-game is running, the taming progress resets to zero and the baby dies.
- Finish the third wave. The Oasisaur is tamed instantly when the mini-game completes. The creature whose Death Essence you used is destroyed in the process, so use one you are not attached to.
- Mind the 24-hour cooldown. For the first 24 hours after taming you cannot immediately revive a creature with it — resurrections only work once every 24 hours, and the creature used in the taming progress counts against that limit. It is currently unknown whether a failed mini-game also starts the timer.
Why the method is what it is
The creatures that break the knockout rule are the ones players search for by name, because the standard trap does not apply to them. This one follows its own rule, and the guides that treat it like a Rex are the ones that waste the attempt.
The three ways this goes wrong
- Using a Death Essence from a tame you want to keep. It is destroyed when the mini-game completes.
- Letting the baby take a hit. Damage to the clone resets the whole bar to zero, and the third wave is level 121 vultures.
- Rolling the dice on a low-level weapon. The waves escalate in level, so a weak rifle that handles wave one will not handle wave three.
A quick checklist
- A Death Essence from a disposable tame.
- A Fabricated Sniper Rifle or Longneck Rifle with plenty of ammo.
- Grappling Hooks or a flying mount to get onto its back.
- A clear area — vultures spawn from around the oasis.
