Actually I suspect it won't work in the damage toggles. I have the Reactive Core Radial, and it doesn't do the damage on my elec/spine tanker which has 2 damage auras. It does work on AOE click attacks just fine though, so throw spines or spine burst will kick off the DoT just fine.
As I recall from the days of live COH, they actually stopped interface from putting the DoT on the damage auras because it was letting them do utterly stupid damage. Each tick had the chance to do he DoT and it happened so much things just melted. I remember having this effect on my elec/elec tanker back then. I was able to solo a rikti pylon because the effect was so broken.
