Family Events

Faction Events are uncommon events which have a 2% chance to occur, and are signalled by a line of pink text at the beginning of a stage. Faction Events restrict the kinds of monsters that will spawn during the stage to specific, limited selections depending on the event, including those spawned by and during the Teleporter Event.

Some events can result in certain monsters spawning in Environments they otherwise wouldn't be able to (eg. Stone Titans in Rallypoint Delta).

Due to this check using the standard RNG instead of the stage RNG, it is possible to get this event while doing a Prismatic Trial - this occurence is random however. It is unknown whether this is a bug or intentional.
