Orb Vallis, home of the Corpus, is an open-world map on Venus inWarframe. While exploring Orb Vallis, you may come across cracks in the ground that are spewing out an orange liquid. These are Thermia Fractures, a type of recurring event you’re able to complete for a variety of rewards.

There are a few different steps you have to take to complete each Thermia Fracture, and with no tutorial in-game, getting started can be confusing. For starters, the event only occurs about once a month on a somewhat random schedule. Luckily, that’s where we come in. Below, you can find everything you need to know about Thermia Fractures, including how to start and complete them, and what the rewards are.

How To Complete Thermia Fractures

Before you start a Thermia Fracture, you will need to collect aCoolant Canister. This carryable item drops fromCoolant Raknoids, which can be foundfollowing the Exploiter Orbaround theTemple of Profitin thenorthwest corner of Orb Vallis.

Once you have the Coolant Canister, find a Thermia Fracture, which are thecracks with orange liquid spewing from them. Here,insert the Coolant Canisterto begin collecting the Thermia.

Doing this will causewaves of Corpusto attack you and the Canister while it fills up over a3-minute duration. This willfill the Canister to 25 percent, at which point you will need totake it to another Fractureand repeat this process until it is fully filled.

Completely filling a Canister will reward you with one Diluted Thermia, which is used to fight the Exploiter Orb.

Alternatively, you canload multiple Canisters into the same Thermia Fractureand fill the whole thing in one go.Additional Canisters must be added within the first 30 seconds of the defense starting, so you’ll want to carry them all over to the Fracture beforehand.

Either way, once the Canister has been completely filled, you’ll need to find another Coolant Canister from a Coolant Raknoid to continue closing Thermia Fractures.

During a Thermia Fracture, there are several different modifiers that can occur, affectionately referred to as ‘Burps’. Here’s a list of each type of Burp and what it does.
