Voidwalker is currently being carried by Devour and Child of The Old Gods! That is due to Chaos Accelerant losing its 30 percent Damage Buff and that the Charging of Grenades isn't worth it. Since Choas Accelerants' effects either make Grenades worse or are so outdated, they are better at just using a weaking fragment or a fragment that actually improves a series of void grenades. But that's for a different discussion. This leads me to say that the child of the old gods has many drawbacks to kamaizakizing it's self into walls, ledges, the skybox, or simply staying by your side in gunfights. Having a delay before begins to apply weaken and just the damage being bad. Especially if you run empowring rifts to try and gain health regen for sacrificing your healing rift. Which a mass majority of players don't even know that child of the old gods functions differently with an empowering rift. A change that I feel would drastically help the child of the Old Gods would be by default you could Repick up The Void Soul. So you wouldn't need briar bind, especially since, as previously mentioned, it kamaizakizes itself. This would allow you to not be shoehorned into Briarbinds and let you actually try out better builds. Also, going from 2 fragment slots to 3 would also be a warm welcome fo the childd of the old gods. Also, if Damage Dealt from an empowered child gave Dark Matter Healing Returns on each tick, I could see myself actually using an empowering rift. To make Briarbinds worthy of using it, you should gain the option to consume your own child after you activate your rift normally. Consuming your own child applies a weaking curse around you. Applying weaking around you for a short duration increases ability regen or health depending on your rift. Successful kills while weaking are applied grants escalating damage to your weakening effects and its timer refreshes.
