Return of Reckoning

Safe to say that Crown of Fire + Fueled from Within Tactic setup is pretty nice in a party of channelers? Something like an Ether Dance SM, Whirling Axe WL, Rapid Fire SW, Rune of Burning RP, Withering Heat BW, etc. Or am I mistaken and Flames of Rhuin doesn't interact with channeled abilities like I think it does?

AFAIK it does work on channelled abilities cause FoR applies to every damage tick, will test today to be 100% sure

It works, so does the sorcerer's Frozen touch.
