Solus Control Unit

The Solus Control Unit is a new Boss Monster introduced in Risk of Rain 2. Being a Boss, the Solus Control Unit may be encountered after initiating a stage's Teleporter Event. It can otherwise spawn naturally during higher difficulties. It is exclusively found on Siren's Call.

Skills & Behavior
When the "Solus Control Unit" is initially fought, it only has two abilities available to it: the first is a charge shot where it will fire light blue orbs from set points on its body at the player, that will constantly explode in a small area. Each explosion has a Proc Coefficient of 0.02. The second is the ability to summon 3 Solus Probes, of which it does so at random intervals. After dropping below 50-65% of its maximum health, the Solus Control Unit will then begin to periodically do an attack where a large blue circle will appear on the ground around a random opponent. This circle after a delay of approximately 5 seconds will explode, dealing massive damage in a very large area to any players left inside, as well as launching them into the air. Note that players are slowed when caught in the circle, making it more difficult to escape their explosion radius. The explosion has a Proc Coefficient of 1.0.
