Fear Me!
For Great Justice!
Holy cow. This is for fighting those self/absorbed monks who think that they can stand there and not need to run. [yay cripple!] I think with the boost from Locust's Fury and For Great Justice, you can spam Fear Me, like, every 2nd attack... or less!

With a lack of speed boost, you can't escape, and this build wasn't built for it. To keep Fear Me! at max effectiveness, you need to keep swinging at your hapless victims and rely on teammates [hopefully competent ones] to keep you above death's grasp.
Thankfully, anti-dmg enchantments won't stop it and stances are pointless due to Expose Defenses... They can't run due to cripple and if you can keep up the pressure with Fear Me, they'll be low on energy to remove it again, if they're kiting you, they're not healing their teammates [can't run and cast at the same time...

Of course, hexes and conditions on yourself like, blind and Soothing Images would put you out but hey, no build is perfect, right? ^_^
