The final unit to add to my 'Creations of Fabius Bile' Warband is a Slaaneshi Cult of The Iridescent Wings - a group of radical avant garde artists who have gone just a leetle too far in their love of bright new abstract art to sweep away the fuddy-duddy Imperial Realism style.
I play these just as ordinary cultists from the Chaos Marine Codex.
Yes, they look the part of elite troops, being fabulously wealthy from selling their art to decadent aristos and so able to afford the finest black market weapons BUT they are artists, for Emperor's sake, not Imperial Guard or even a Hive Gang.
The Supreme Creative, as the Cult Leader is grandly named carries an electrified staff of authority (brutal combat weapon) and an autopistol.
Any model armed with a long barrelled weapon is deemed to be armed with an autogun.
Note the iridescent sheen on his greatcoat.
Models with pistol(s) are deemed to have an autopistol and brutal assault weapon.
The hand-flamer is treated as a 'flamer' for the purposes of game play.
It spews out iridescent purple flames in honour of Slannesh.
