This is my attempt at a fluffy (but, for the time being, Captain Alberec-free) Exorcists list. I will be trying out Captain Alberec, too, but 1) in general I prefer librarians, 2) it's going to take me a while to amass the bits I'll need to kit-bash the Exorcist's special character, and 3) not all opponents will let me play with a Forgeworld character, so I'll probably be using some variant of this list, even into the future.
Here goes:
HQ
Librarian
Elites
10 Tactical Terminators (2 Assault Cannon, 2 Heavy Flamers, 2 Chain Fists)
Dreadnought w/Plasma Cannon, Power Fist (built in Heavy Flamer)
° Drop Pod w/Locator Beacon
Troops
10 Tactical Marines (Melta/Melta), Sergeant w/Power Weapon, Meltabombs, and Teleport Homer
° Rhino w/Dozer Blade
10 Tactical Marines (Plasma/Plasma), Sergeant w/Power Weapon, Meltabombs, and Teleport Homer
° Razorback (Las/Plas) w/Dozer Blade
10 Scouts w/Camo Cloaks (Missile Launcher, 4 Snipers)
Fast Attack
Stormtalon w/Lascannons
Heavy Support
Land Raider Godhammer
The goal is to create a force that reflects the vaunted tactical flexibility of the Exorcists. I've got some heavy deep striking, and a lot of it is rendered very reliable by locator beacons, teleport homers, and the natural qualities of drop pods which means I can put things exactly where I want them. I've got a lot of options for combat-squadding my units so I can create versatile units or specialized units, depending on the situation. Everything has a ride, and even my heaviest tank can carry troops and help claim objectives.
Long and the short of it - what do you think?
