How do you execute an underboss?

Need to meet requirements which includes execution ticket.

They can only execute you if you haven't bought death syrup to fake your death. Your underboss goes into a moribund state = faints then lays still pretending they're dead until you make good your escape.

If you capture an underboss who is from a settlement over level you can execute them.

Depending on the level of your hostage cell, it can take up to 3 days to execute them.

You have to watch for other players trying to get the bounty by attacking you and they release the underboss you captured.

I went into hiding after I captured the underboss. Now I have only 22 hours left.

In order to execute, your turf and the target's turf must be Level 17 or higher. If you capture an Underboss from a turf between 10-16, the Underboss will be released/escape.
