Build ideas around Deviants crown

So recently I've found

Initally it seems insane, but the more I've looked at Amazon builds, they are relying heavily on their devotion skull, and often skill after that as well. Anybody got idea what build could work well?
And what is the "strength factor to spell damage"? Is it strength scaling your spell damage? Or the same as energy factor, but for the strength and attacks? I'm confused by the wording tbh.

The same as energy factor but it uses your str to calculate the bonus spell damage instead of energy. Apparently bullshit! Strength factor pretty much acts as a bonus to your energy factor - read more in the next comment.

600 is pretty damn near reaching max bonus dmg without much points in either energy or str. You are looking at +450% bonus spell damage here @5000 energy/str or 426% @4500 or 405% @4000 beyond 5000 is barely goes up anymore 450% @6000 or 453% @100000

The same as energy factor but it uses your str to calculate the bonus spell damage instead of energy. 600 is pretty damn near reaching max bonus dmg without much points in either energy or str. You are looking at +450% bonus spell damage x2 here @5000 energy/str or 426% @4500 or 405% @4000 beyond 5000 is barely goes up anymore 450% @6000 or 453% @100000

The part about the Strength Factor/Energy Factor is not correct. The sum of the two boni is capped at 200 % while calculated the same way (Factor*stat/15000) and you only gain one stat-only synergy (260*(stat+10)/(stat +250)) depending on your spell. So max Synergy is about 450% but you reach it more easily with this crown.
Sorry for spamming my own thread but for a more in depth look to Spell Synergies you can also have a look into this topic

[edit]On topic: Maybe try a heavy phys damage barrage bow build with rest of the gear is concentrating on Spell procs that benefit from the Synergy[/edit]
