It could be an excellent option if Clap will work on storm calling when/if it gets fixed.
Dark Sight, in theory, should work well with Dance. As it makes you immune to several aoe effects and hides you from enemies.
Just do make sure youāre not too close to allies, because regular attacks can still hit you and interrupt it.
Storm Calling also boosts Physical dmg with itās debuff btw. So if you can extend storm calling + keep dance up for 40s (with divine might and broom) you could add a good chunk of physical dmg.
I think it means that any physical dmg deals +10% extra dmg as holy dmg. (per skill level ofc.)
Might get the answer from here https://youtu.be/Do5UBa-4VbQ, that miko keeps using dance alongside a fencer.
