Triggers mutation in a serpentine helm.

A tanzanite mutagen is an untradeable item dropped by Zulrah. It allows a player to cosmetically recolour their serpentine helm to a turquoise coloured tanzanite helm.

Drop rateEdit

The drop rate for this item is calculated from two different rolls: The chance of rolling Zulrah's flax table (1/25.6) and the chance of rolling the mutagen table (1/256).

Thus, multiplying these two fractions will result in 1/6,553.6, which is Zulrah's chance of dropping a mutagen, or a 1/13,107.2 chance of the desired mutagen.

However, since Zulrah gives two rolls to its drop table per kill, the chances are doubled, giving a 1/6,553.6 chance for a specific mutagen, or a1/3,276.8 chance for any mutagen.
