This build utilises efficient charge stacking through Precursor's Emblems and the Supreme Grandstanding Timeless Jewel node with The Annihilating Light on a weapon swap set up to do enormous damage and clear with Discharge. Due to massive spell damage amplification from Pain Attunement, Righteous fire and the amount of charges generated, in combination with Crackling Lance of Disintegration, 85% shock is achievable on Pinnacle bosses.

Golems are immune to elemental damage, revive after 4 seconds and have around 4x effect of buffs due to the Elementalist ascendancy options. The build is quite tanky, capable of mapping and bossing, though lacks spell suppression. It is an extremely good Blight, Legion, Abyss, Breach and possibly Simulacrum farmer, from what I have tested.
