How to obtain:
Flame dye rolls from killing an Inferno Demonlord. It is currently unknown if the dye rolls for the owner, killer, or all participants of the boss.
Flame dye's base chance depends on the tier of the boss. At tier 4, the dye has a base 1/500,000 chance of dropping.
As a dye dropped from a slayer boss, it is not affected by magic find or looting.
There is a rng meter for this dye to guarantee a dye after 75,000,000 progress. It is very unlikely to drop the dye before reaching 100% meter.

Method:
The fastest way to get the dye is from killing tier 4 bosses in the smoldering tomb in the crimson isle.
