Heart of the Praxic Fire

For a Voidwalker I recommend using the Obsidian Mind helmet.

If you can get it all, then use these: Bad Juju, Obsidian Mind (helm), and void walker with soul rip on. Together, this will allow you to spam nova bomb.

Sunsinger Main Perks: Fusion grenade Fireborn Flameshield Perk that gives recovery and agility Perk that goes all into agility Perk that gives two grenades Armor: I really want HotPF but I'm using the Claws of Ahamkara simply for the double Flame Shield. I stack discipline because I love having a crap load of grenades to throw when using radiance This setup allows me to tackle many different positions considering the high agility allows for speed and the recovery/flame shield allows me to Scorch enemies constantly without worrying about my health which happens a lot with Voidwalker. If I ever get HotPF, I change my perk to Radiant Skin instead of Fireborn so I can get the max usefulness from it.(except in nightfall a I'm sure) Weapon wise: I never really stick with any single weapon because I can't seem to find that one that really works for everything. Fatebringer used to me my go too but it is losing it's touch as the DLC's get here. Other than that, right now I'm using Thorn, LDR 5000 sniper(solar), and Hunger of Crota.

Bad juju and obsideon mind or claws of Amikara and mida multi tool

Heart of Praxic Fire made me fall in love with the Sunsinger in Crucible.
