Actually you should consider:
Canary Diamond of Sins for the waning boundary imo.
Its crittable spell. Void void void!
However a DT friend of mine insists his 23 magic dmg will do him better, as this canary diamond only procs from melee hits.
Thing is this is 5% chance gem, not 2ppm. So with multiple mobs it can proc infinetely. But this can go both ways. 2ppm will force a proc eventually, 5% chance can keep you unlucky chain forever. Or the other way around
