Imminent Detain

Imminent Detain is a debuff in the Vault of Glass raid. A random player receives it and has about five seconds to move away before a Vex dome encloses them and anyone standing close. Teammates outside the dome can free the trapped player by shooting it.

It appears in two fights: after the shield breaks on the Templar, and in the damage phase against Atheon, where it is applied to a portal team member once Time's Vengeance reaches 15 seconds. The player who receives it should move well away from the team so the dome doesn't trap everyone.
