Sharing my own little build i put together the past week and turned out pretty well.

Wanted to make use of the new weapon enchant that triggers a fire skill on hit. Combined that with Lightpoacher spirit charges that gives a lot of phys as extra elemental damage.

To sustain spirit charges even on single target i used the new ring The Hateful Accuser to gain Penance Mark that spawns killable phantasms every second on hit.

That interaction allows me to abuse on kill effects even on single target, like increased damage if killed recently and the main reason, sustaining spirit charges.

On top, triggering a skill does not count as using it, when I keep channeling cyclone (my trigger skill) i can keep spamming tornados without expanding spirit charges at all, which makes it very easy to keep maximum charges all the time.
