Band of the fanatic ring swap bug
I tested this many times using only heatwave for the dps source . Once your dot starts you can quickly swap rings after your Dot is active and the dps climbs higher . my actual theory is when red ring of death triggers then you swap rings it causes the interaction. In the game swapping band of the fanatic for burden of the destroyer has yielded the best results and the dps climbs a good bit.
Also even though I'm focusing burn damage Energized Neck Coil far outperforms talisman of the sun. I swapped out different archetypes back-and-forth too between invoker ritualist alchemist and archon ,ritualist/alchemist gave me slightly higher damage than ritualist/invoker.
On a side note playing around I learned Wrecking Ball makes Neck Coil crit pretty hard but that is something to play around with at a later date lol.
