not rolled by the roulette
Galvanic Field is a spell that grants a buff which grants additional shock chance when cast. Upon shocking an enemy, the buff is removed to attach an electric field around the target, which hits a random enemy within its area of effect to deal lightning damage for a duration. The field has increased area of effect and damage based on the magnitude of the shock that was applied.
Captainlance9 made a really cool build around this back in October 2023.
Level requirement: 16.
The roulette doesn’t roll this gem, so its delivery options haven’t been worked out.
