Light Sorceress
This Sorceress is decently solid but really starts to pick up in damage once Infinity becomes available to her. Conviction Aura is known for best breaking Lightning Immune Monsters, leaving them vulnerable to the extremely high damage of the Light Sorceress. Once this item is obtained she can virtually farm any area in the game without concern.

While she may have good resistances and mobility compared to a Javazon, it is easy to teleport into the wrong spot and die quickly.
