A magma mutagen is an untradeable item dropped by Zulrah. It allows a player to cosmetically recolour their serpentine helm to a magma helm. The mutagen is consumed upon use.

Dropping monsters

Monster	Combat level	Quantity	Rarity

Drop rate

The drop rate for this item is calculated from two different rolls: The chance of rolling Zulrah's flax table (10/249) and the chance of rolling the mutagen table (1/263). Both mutagens are equally likely.

Thus, multiplying these two fractions will result in 1/6,548.7, which is Zulrah's chance of dropping a mutagen, or a 1/13,097.4 chance for a specific mutagen.

However, since Zulrah gives two rolls to its drop table per kill, the chances are roughly doubled, giving a ~1/3,274.6 chance for any mutagen or a ~1/6,549 chance for a specific mutagen.

Changes

Date	Changes
22 November 2018 (update)	The drop rate was very slightly increased from 1/6,553.9, due to technical limitations as crushed nests were removed from Zulrah's drop table.
