I used a combination of Death Company, Grey Knight (for the back/psychic hood, right shoulder pad, and staff) as well as Sanguinary Guard bits, along with the Blood Angels upgrade sprue, and a smattering of bits from the Blood Angels dreadnought, and Blood Angels tactical squad box. I also had a spare jump pack from an assault squad box I used as well.
This is the final result:
Parts list:
Sanguinary Guard legs, and possibly head (Can't recall exactly where I got the head from. It's either from the Sanguinary Guard box, the Death Company box, or the Blood Angels Tactical Squad box)
Rear torso, right shoulder, and staff are all Grey Knights bits. Rear torso with the psychic hood and right shoulder are from the power armored
GK box, and the staff is a warding stave from a
GK Terminator box.
Blood Drop in the center of the head of the staff is from the
BA Tactical squad box (Minor conversion I did)
Front Torso and left shoulderpad are both from the
BA Upgrade Sprue
Jump Pack is a standard Assault Marine jump pack from an assault marine box
Large purity seal on the right side of the
JP and winged Librarian emblem on top of the
JP are from the
BA Dreadnought box
Purity Seal on the bottom of the right pad is from the Death Company box (I think)
Right arm (sans Hand and staff) Is from the Death Company box (Just the arm, can't recall if it's a bolt pistol or chain sword arm before I cut the hand off to replace it with the staff). The Left arm + pistol is also from the Death Company Box.
Hopefully that helps provide some inspiration.
Best of luck, and take it easy.
