Hey so currently the only place you can get the classic worm cult style is the Worm's raiment set in Vaults of madness, and I can confidently say that a great many people love this set, and for good reason as its easily one of the best looking necromancer themed sets out there... but are dissapointed to be forced to wear the worms raiment which is not great for all builds and is outclassed by newer sets.

Whilst there are several similar sets people want like this (Lich style, saviours hide style, the asylum weapons and even racial tier 5), the old ashlander styles, soul shriven style, and even the sea viper armour were all added and with the whole Seasons of the Worm Cult (in which the set is still being used on worm cult enemies), I think it would be a perfect to add these as costumes or a motif to the crown store as it fits in perfectly with the theme.
