Tips

With Crack the Egg, Firefox is amazing.³
For an energized autocast build, combine Runecarver, Hexbolt and a damaging autocast augment such as Firefox. Energetic increases the efficiency of gaining Energized stacks, and additional autocast augments can help the build.⁴

Interactions

Firefox can trigger Decapitator automatically.⁵
Whether Firefox triggers Chroma Flux is unclear.⁶
In an autocast loop, Hexbolt can make Firefox trigger another autocast. These autocasts can also stack Energized through Runecarver, resetting the loop.⁷
