Let the Darkness consume you.
Beyond the veil of death,
there burns a black fire.

Blackflame Covenant is a keystone passive skill that modifies Fire spells, converting all fire damage to chaos damage, causing ignite to deal chaos damage, and allowing chaos damage to contribute towards flammability and ignite magnitude.

Mechanics

Blackflame Covenant will also cause your fire spells and ignites to become purple instead of their default colour.

Blackflame Covenant only affects spells that have the Fire gem tag. Spells without the Fire gem tag will not be affected, even if they deal fire damage. The spells will still scale with Fire Skill Level, not Chaos Skill Level.
