Cool. Good to see you've got a WH army up and running. Looks good to me, although we'll have a look.
Inquisitor Lord
Power Weapon
Bolt Pistol
Rosarius
Psychic Hood
Hexagrammic Wards
Digital Weapon
2 Sisters Hospitalisers
2 Crusaders
1 Familiar
-Digital weapon I'd drop.
-Hospitalers are okay. The Inquistor is an independent character, so if he's individually targeted, your girls can save the wound.
-Take excrutiators. If you have anti-psyker gear, then you should take them. They're cheap, fluffy and useful
-I'm not a fan of Inquistors at all and yours is a good example. Geared for CC with like 6 strength 3 power weapon attacks. For the cost of the unit, I could get a banshee squad (not comparing lists, just effeciency). He's okay, but not the biggest threat to deal with
*You can only have 1 Assasin (you have two
E listed with 110pts)
*Two squads are two small. They need to be 10 girls minumum. I'd consider boosting them up to 14-16 girls though.
*Books of Saint Lucius is the most important piece of wargear in the whole army. To have LD done on unmodified 9-10 is the best thing to happen to this army. I've had my Canoness out-numbered 4:1 and remnant squads fighting dreadnoughts but kept fighting anyway because of this miracle book. I'd consider it compulsary for your Canoness to have one. Your Seraphim Veterans should have one each, because when your a high priority enemy and in assaults a lot, you want to pass all the moral checks as possible. In games over 1200pts, I have books for all squad leaders, but you really only need them for your HQ and squads in assault (if you face a Librarian with fear the dark, then maybe or squads should have them)
*Drop the holy prothelium and get extra armour for your Exorcists. Immolators don't survive long and extra armour is a great upgrade for Exorcist tanks.
*Consider giving your Veteran a storm bolter in the storm squad. Bit over-priced, but 6 shots on the move and extra shots stationary makes them a good ranged unit.
*Consider power weapons for your Veteran superiors as well
Have fun
