Equipment
Runes of Superior Scythe Mastery, Superior Earth Prayer, Superior Mysticism, and 2 superior runes of your choice, though not Vigor runes
Any kind of armor other than armor with the survivor insignia or health boosting runes will do, as long as it has a total of 5 superior runes on. Note that armor level does not matter for this build, so a set of armor purchased in Kamadan will serve this builds purposes just fine.
A customized Scythe with a "Guided by Fate"/"Strength and Honor"/"To the Pain!" inscription. A scythe grip of Enchanting and a Sundering or Zealous scythe snathe can make things easier.
A Zealous scythe is recommended while facing only one foe; if you don't use one you may not gain enough energy to recast all 3 enchantments. Note that energy management when facing a single foe may become easier by dropping Balthazar's Spirit.
Mystic Regeneration is quite effective at keeping your health up, however enemies with fast attack speed or powerful health degen spells can render it useless. Try not to face your target alone, make sure he has company so that Mystic Vigor triggers more often. When you aggro a group, make sure they are more or less mobbed up.
Counters
Anti-Melee will reduce damage, but Vow of Strength will still hit through miss/block.
Interrupts/Knockdown/Daze
Enchantment removal.
Health Stealing/Loss will bypass Protective Spirit.

Make sure to always ball groups so that your Scythe attacks will hit all foes.
The group should now be dead. Keep going right along the sea, as the run ends near Kegai.
Please note that unlike many other Jade Brotherhood farm builds you can also engage groups with Jade Brotherhood Mesmers. In that case, during the fight recast Protective Spirit and Mystic Regeneration as soon as you can.

Head north from Jennur's Horde, taking the path directly to your right when entering Vehjin Mines. You should see a little underground passage where you'll find the first Behemoths.
Take the Monster Hunt bounty from the Shrine if needed.
Under your prots and Mystic Regeneration, walk through the passage and aggro all three Behemoth groups here, including Marobeh Sharptail's group.
Use the Right Wall Block technique [1] to ball all three groups.
Repeat the same procedure with the groups near the portal to the Holdings of Chokhin. You can usually take on up to three groups at the same time on average.
Rezone using the portal if planning on doing multiple runs.
There is usually a Locked Chest in the area.
Your path.
Variants
Vow of Silence: Prevent dangerous spells such as enchantment removals and interrupts. Renewing your other enchantments may become difficult.
Armor of Sanctity and Eremite's Attack Instead of Mystic Vigor and Banishing Strike. Can tackle larger mobs and gives bigger spikes. But may be difficult to keep up.
Notes
Unlike the traditional Invincible Monk, Death Penalty is not an issue with this build. If you die once, you can still run it fine, it's actually easier if you have 58 health. Same goes if you die twice. If you die 3 times, swap out one superior rune (put on one piece of your normal armor). Experiment with different normal armor pieces and different scythes on. You'll eventually get to a value below 100.
