Question on aumentation stacking

[zubad]

I want to use two Diverting Fastening (jeweler, deflection-triggered heal proc), one fro each wrist.  Does anyone know if this augment will stack with each other for two wrists?

I would assume no but I am not sure.  I find the mit adornment helps more than the heal procs though.

Both will have a chance to proc, but the effects will over-write, not stack.  So for example, if the first one procs and you have two heal tiggers left when the next one procs, you will effectively lose those two triggers and the proc will reset (essentially the same thing that happens if a sigle effect procs twice in rapid sucession).  Having a second one will effectively increase you proc rate, but the effects are less than double.
