Need help with Berserker Volcanic fissure of Snaking.

Cannot find a good place to use Glories Vanity jewel for Corrupted soul.
Put in L/H side near Elemental Mastery and loose 50% ele damage.
Put it L/H side next to Arsenal of Vengeance and have to loose 4 points from somewhere to use it.
Use it in the bottom middle and it changes my End and Frenzy charges.

Use Path of Building or take all three slots and look at transformed small passives and notables, they can be good.
