It's a Trap

It's a Trap is an event quest in Fallout 76.

Quick walkthrough
The Scorchbeast detector has gone off, reporting an attack. The dwellers need to lure the Scorchbeast to the marked location and trap it so that it is grounded, at least for a while.

The event requires players to first activate the lure, then kill the scorchbeast once it's on the scene and trapped. Notably, the trap will keep the beast grounded, making it easier to take out than fighting it as it flies above the Mire's canopy.
