Chaos Axe

Description
The Chaos Axe is an impressive-looking axe that looks like it has been fashioned out of solid blue-white light. Chaos Axes are highly desired for their rarity and their unique appearance.

Chaos Axes can be seen in the hands of Skeleton Berserkers in the Fissure of Woe, as well as your Doppelganger.

Location
Chaos Axes can only be found in the Fissure of Woe or the chests that spawn during the Kilroy Stonekin quest.

Dye
Dye changes the color of light that the Chaos Axe emits, as well as occasionally how large its glow is. Dying Chaos Axes can be tricky, since the resulting color is often completely different than the color dye used. Here's how to get the basic colors onto a Chaos Axe:
 * Red: Blue dye
 * Orange: Purple dye
 * Green: Red dye
 * Light Blue: Dye remover
 * Dark Blue: Yellow + Green mixed dye
 * Purple: Green dye
 * White: Black dye
 * Bright White: Silver dye

There is no way to create a black Chaos Axe; both black and silver dye turn the axe white.
