Easy Rumrunner

[yamahacore]

purposefully get yourself stuck or stall yourself on one of the flags.

you can grab the same marker 5 times to complete the quest early, this works on any of the flags.

afterwards you can swim/glide down

enjoy completing both runs in less than 10 mins

Or you can just go to the first flag on the right, get the flag, despawn the barrel, go back up near the flag, respawn it and grab it again and repeat.
