Thought i put up runningbuild (though not for running missions) i use on my dervish, so far haven't failed to run anything.

harriers haste
vow of silence
dark escape
dash
vital boon
mystic regeneration
"i am unstoppable"
faithful intervention



pretty straightforward, cast faithful intervention at start, cycle runningskills, before passing enemies cast boon, mystic regeneration and if passing any casters vow of silence use i am unstoppable when crippled or getting hit by ranger arrows

for run to droknar's forge you're best off using fleeting stability instead of unstoppable for longer duration only drawback you need to remember that you can't cast it after you cast vow of silence but a little practice and you'll know where and when to cast it
