as said F9W9 vans are the way to go, huge defence, high attack, 2 flaming attacks, high speed, reasonable protection and a shield (which incase you didnt know gives a 50% chance of blocking a ranged attack). the pretender that gives this bless makes great artillery and can fight nicely too with buffs likequickness, breath of winter and fireshield (which combined with lvl 9 fire completely owns).
for your castle a good choice is a watch tower, you dont need many resources to produce vans and its cheap enough to allow you to make a few (which means more vans can be made
). with a double bless you'll want high dominion but that along with the cost of 2 lvl 9 blesses means you need to take bad scales. I've just tested without cb mod on (although im not sure if patches changed cost of moloch/his magic ect) but what i got was:
F9W9 Moloch
watchtower
7 dominion
sloth 3
death 3 (it has almost no impact unpatched/modded)
cold 1
order 1
also if your using van herse's as thugs give them a blood thorn, its a life drain weapon (therefore it rocks) and single handed so you can still use a shield (try blood thorn, lucky coin and possibly horror helm/horned helm since fear/another flaming attack is always good and rime hauberk/other armour since cold radiation/other good armour is useful too. also consider cat charm (because extra defence+ vans high defence+W9 rocks) and/or ring of regen/amulet of anti magic.)
and if you guys have another game and you really want to show them why they should use CB try caelum spamming false horrors. get a bunch of seraphs/high seraphs and script them to quickness, summon false horror, summon false horror, summon false horror, summon false horror cast spells.
it only costs 10 fatigue unmodded (compared to 30 modded) and is pretty deadly.
