This has probably been posted before but this is a my build for PvE and (Story)Dungeoneering: Basically ‘zerker gear. Runes of the Traveller for mobility. Staff and Sword/Focus. Have a Greatsword in bags for ranged fights (Like for Golem and Door Guard in CM Story ((Don’t salvage it >.>)).
Traits: 6 in Chaos with IV, X (for survivability) and XII (Because sometimes you cloak peeps.)
4 in Inspiration with II (for Feedback and Null Field) and X (for the two mantras; handy for group healing)
4 in Illusions with VI (for the fields) and IX (for the blinds)
Healing Mantra, Feedback, Null Field and Mantra of Resolve (which can be swapped when needed)
Basically: You can pull by charging into combat, with staff out, press 2 and then drop a bunch of clones (press 3, 4 and drop 5) then get in close and swap to Sword/Focus.
Staff 2 will generally get you out of stuns or bad situations. Sword 2 will evade you and does nasty things to groups in range. Focus 5 is nice for groups too, and 4 can speed you and your buddies, slow pesky enemies and cause mayhem if you randomly press 4 again (trick: put it near a wall, then they all slide into the wall).
As you channel and complete mantras, you heal yourself and your buddies. Mantra of Recovery is your personal heal. Mantra of Resolve is great for removing conditions on your group and yourself. Resolve is especially handy in TA Story, among others.
Feedback is great to pop on Snipers, Archers and the other ranged enemies everyone forgets. They can then shoot themselves! It also works if you’re within the field and an enemy is shooting at you. Since it’s a glamour spell, your talents mean that enemies in it are blinded and confused, so pop it over melee groups too. Null field produces the same blind/confusion effect, and adds extra condition removal for your team.
I find this build to be quite the workhorse in groups. My survivability is impressive. With the traveller runes, my boon duration is longer and I have far more mobility which equates to even more survivability. It is a consistent movement increase rather than relying on Focus 4 for speed, which will run out.
The DPS is not too bad, but your role is to assist the team and help keep them cleansed, buffed and rolling as well as providing support. It’s best if the team can stay within your fields, but this can’t always be the case.
I’ve yet to run Arah as a Mes, but the theory of extra length and boons on cloaking should work well here too and in any other situations requiring portals and cloaking. Hope you enjoy!
