Ok, so basically, have the user press a button that sends a notification “defeat 5 sentries”
Then, activate a waypoint that shows where the sentries are.
Have a counter count up whenever a sentry is destroyed.
Make the counter’s target 5 and starting value 0.
Wire the counter to a deactivated button. When the counter reaches target, activate button.
Now when the player goes back to the quest start, have them press that button and get their reward!
