On x-mas day Black library released ”Cypher lord of the fallen” Dataslate. It contained rules for Cypher and a formation of 1-3 units of chaos chosen. he and his formation can ally with SoB, IG, BA, SM, SW, and CSM. NO DA or xenos. Like the inquisition the don't count tward the 1 ally and dont take up any FOC slots.
Cypher is pretty boss. Ws 7, Bs 10, I 8 are the eye popping stats. He's got a laundry list of special rules. A few are fleet, hit and run, ATSKNF, shrouded, eternal warrior, and more. He can shoot his pistols twice each in the shooting phase or once and run. His cc attacks also use his pistols half boltpistol and half plasma. Oh and overwatches at full Bs 10.
His chosen formation gets infiltrate(like the old chosen did) and if within 12” of cypher they get ATSKNF and use his leadership of 10.
Lots of cool fluff too. It is a little expencive @$17. But a must have for the DA and chaos fan like me
