What do you need?
3 heroes(of any flavor preferably 2 rangers and 1 assassin you dont use)
a mouse(gosh why wouldn't you have one?)
If your like me and use 2 rangers and 1 assassin then you can save time from draggering and dropping and use these templates
Rangers:
OgcSc5PPTwUDrUnBAAAAAAA
Assassin:
OwJSg5PPTwUDr8XrzAAAAAA
Party order:
You//Ranger//Ranger//Assassin//Devona+Lukas
=IMPORTANT=(kind of)
If you want to DECREASE the length of each run bring Godspeed, "Fall Back!", and "Make Haste!", All paragon shouts set a hot key to target your second party member or which ever spot in your team runs Stairs so that you dont need to click on the Stairs runner.
No runes and such needed unless you have the money and don't care about the hero.
Step 1 The first flags
This part is simple you have to set 4 flags the first for your top ranger in the lake, the second at the shore point, third at the mushrooms, and 4 at bridge.
Flag in this order
Stairs(will be reffered to as 1)
Shore(as 2)
Mushrooms(as 3)
Note: Flagging Shore up to high will cause a body block be sure to flag near the water or in it find out your exact leeway and use it
Practice the Mushrooms point, as a proper flag will mean you wont have to reflag there.
Note: Flag the rest of the party(devona + lukas) ACROSS the bridge not on it if you flag directly in front of the bridge they will never get body blocked don't flag in a diagonal line or it may cause problems. generally you can just have 1 run bridge but bring 2 as one may die IF you have to drop one have the leecher bring a hero and run it.

Once your first ranger has its shadow form run out or a few seconds before it runs out flag it to the second point(Red dot in the picture below) since flagging ON the stairs is pretty tough flagging at the top of the stairs where the giant ramp to the jade quarry is, is the best spot so flag right under there just like in the next picture it offers a larger flag point so its harder to mess up and force you to re flag once you have flagged there you can grab the quest and wait till your rangers health is at 50% and it should be done.

Practice each point learn how much leeway you get at every point the red dots are about the amount you get
Big=Alot, good luck failing
Medium=Enough that human error isnt a problem
Small=You may have to reflag if you dont hit it.
Skill Order(begin skill chain AFTER all 4 points have been flagged):
Shadow Form 1\\\ Shadow Form 2\\\ Dash 3
Dash 1\\\ Dash 2\\\ Shadowform 3
Run skills 1\\\Run skills 2\\\Run skills 3
once SF runs out on 1 Make second flag, grab quest wait....Done.
Good luck may your runs be swift and painless!
