Chaos (mechanic)

“Chaos” is a gameplay mechanic in Dark Souls.

Overview
The Chaos concept is associated with the lost city of Izalith, and applies to several things, from imbued and upgraded weapons, to specialized pyromancies, and a host of demon enemies.

General Information
Chaos is an effect possessed by specific weapons, that can be attained by either upgrading a weapon down the Chaos Upgrade Path or using one that is innately imbued.

Ascension is achieved through Vamos, a Fire +5 Weapon, and the Chaos Flame Ember.

Effects
Chaos weapons inherit the chaotic nature of Quelaag. The Chaos aspect adds Fire Damage to a weapon, but removes all stat scaling bonuses. Instead, Chaos weapons scale with humanity (up to 10).

Chaos Great Fireball does not scale with humanity, despite what the description says. Pyromancies can only be improved by upgrading and ascending the Pyromancy Flame used to cast them.

Weapons
The following is a list of weapons that are innately imbued with the Chaos mechanic.
 * Chaos Blade
 * Quelaag's Furysword

The following is a list of weapons that were created by chaos demons but do not have the Chaos mechanic.
 * Demon's Catalyst
 * Demon's Great Hammer
 * Demon's Greataxe
 * Demon's Spear

Lore
The concept of Chaos predates recorded history. In the Age of Ancients, the Witch of Izalith and her Daughters of Chaos used fire sorceries to weaved great, powerful firestorms. At that time, the Witch and her followers were flame sorcerers who lived in the city of Izalith. Blacksmiths of that ancient city crafted powerful weapons using Chaos arts. Thus, during the earliest known ages of the world, Chaos was a powerful force.

Eventually, the Witch of Izalith attempted to duplicate the First Flame. What she instead produced was a twisted being of chaotic fire: The Bed of Chaos, source of all demons. Several of the Witch's daughters were transformed into chaos demons, and her son became the monstrous Ceaseless Discharge.

Gwyn’s silver knights fought back against the encroaching chaos demons. However, near the end of the Age of Fire there is no force to keep the demons in check. Chaos demons have spread to all corners of Lordran and beyond, as evidenced by their presence not only in Lost Izalith and the Demon Ruins, but also in Undead Burg, Undead Parish, The Catacombs, Sen's Fortress, Anor Londo, Painted World of Ariamis, and the Northern Undead Asylum.
