The Chaos Flame Ember is a weapon-enhancement tool in Dark Souls.
- Ember required for weapon ascension. Chaos Flame Ember is an art of the lost city of Izalith. Handled only by blacksmiths knowledgeable in ancient methods.
- Ascends +5 fire weapon to chaos weapon. (chaos weapon can be reinforced to +5)
- Chaos weapons are demon weapons augmented by humanity which inflict fire damage.
Found in the Demon Ruins, behind the seven Taurus Demons, in a pool of lava (even if Ceaseless Discharge is defeated). Wearing the Orange Charred Ring while attempting to obtain it is almost necessary due to the high damage lava inflicts when not wearing said ring; however, it is possible to reach it without the Orange Charred Ring. Flash Sweat and high hit points helps.
If Vamos is given the Chaos Flame Ember, he gains the ability to ascend +5 fire weapons down the chaos path, allowing for further chaos weapon reinforcement to +5 (the highest).
