The Vaal Oversoul is a large construct with powerful lightning and physical attacks. It has two main phases. In phase one, it's stationary, firing lightning projectiles and summoning Vaal Fallen. In phase two, it becomes mobile, using a powerful ground slam and a lightning beam. Strategy: In phase one, stay out of the projectile lines and clear adds quickly. In phase two, continuously move to avoid its slams and beams. Lightning resistance is crucial. Use a Topaz Flask if available. Maintain consistent damage output.
