"They can't damage me if they don't exist!"
SADS: Supreme Area Denial System
This build revolves around buffing your power strength out the door with augments, while focusing on range with your mods, allowing you to control when you fire off that juicy [Lavos] ult. It is important not to [Sacrifice] either efficiency or duration in any way possible, as both of those factors will determine how powerful you'll be in the long run. Duration affects how long [Lavos]' status effects last, and efficiency affects how much cooldown reduction you get off of his 3. Personally, I think it is unwise to swap out any of his abilities with Helminith until DE decides it's time to make it so that he can still mix and mash all of his elements even with a Helminith infusion (Seriously, worst idea ever).
