There is an upcoming Tourney at Game Kastle for 1000 points and I am starting to ponder what I would field for my girls. I think at the lower numbers Sisters are pretty effective since they can put out a lot of bolter fire and have some great heavy weapons. Unfortunatley I wont be able to make the tourney but I might be able to help buds out with practice games.
Here is the list
Canoness with Blessed Weapon Book and Bolt Pistol and a Celestine Retinue Melta/MMelta in an Immolator with EA/Smoke and TL Heavy Flamer
3 Battle Sisters Squads on Foot with 1 melta and 1 flamer
1 Retributor Sister Squad with 2 Hvy Bolters and an Immolator with a MMelta EA/Smoke
I wonder if 1 Exorcist is enough since it isnt too much Firepower but I think it will have to do, That Retributor squad might be a wee bit expensive but having 2 immolators might be nice.
