The build is a theorycraft of mine, since it’s awfully expensive to even try thanks to being gated behind massive amounts of grind. The idea is simple: to have as much boon duration as possible alone, and give allies and yourself lots of boons (hence the name pun).

The build can be modified for raids, since basically everyone and their mother runs at least 2 heralds, you could do fine with 50% boon duration, simply switch out Imbued Melodies for Element Bastion, and use different food/utility sources.
You can also substitute Earth for Water and grab the trait that shares auras to allies, the build should do well without it, since only a few aura sources are area effects already.
The rotation would be something like this:
1. Start in Fire and overload it, creating a fire field.
2. Blast it using #2 Dragon’s tooth + #3 Phoenix + Arcane Brilliance (heal) +Arcane Wave + “Aftershock!”.
3. Use Warhorn #5 Wildfire, creating another fire field.
4. (Optional) Wait for #2 Dragon’s tooth to finish cool-down and recast it inside the fire field, since it has a low cool-down.
5. Use #4 Heatsync (by this point everyone, including yourself, should have 25 stacks of might and ridiculous amount of fury , close to 1.5 minutes or more)
6. Switch to Earth and use #4 Sand Squall (it’s a blast finisher)
7. Use Rock Barrier, wait for overloard earth to be ready, and overload it.
At this point you can return to fire to resume the rotation again if needed, or go for air for damage, or water for healing support.
Please tell, me what can be done to improve this idea, and if its viable at all, since I can’t even try it yet…
