Perhaps a Simple DRK Solution

[Chronons]

I would hate to lose Foresight though with their slight deficiency to physical damage, so what I'd actually do personally is this: make LNC/MRD their cross class, and give DRK their own version of Provoke.

I think Sole Survivor is the perfect candidate for this. Reduce its cast time to 40secs and make it exactly like Provoke, then just make its current effect (restore 20% MP/HP on death) a Dark Arts effect.
