Burn

A Burn is the elemental modifier set on a Lost Sector, such as an Arc or Solar burn, that applies to that activity. When you find a Lost Sector on the map, its marker shows the elemental burn and the Champion types to prepare for. Each day's rotation lists two Champion types, drawn from Barrier, Overload and Unstoppable. Burn type and shield types vary by Lost Sector, so check the marker for the current one.

Bring weapons and subclasses that match the burn element. The Legendary Lost Sector version requires completing the normal Lost Sector first and a minimum Power Level of 1800. Legend versions only appear once all normal Lost Sectors are finished.
