i think the choice of the home base Needs help,
cause the Inn is the most obvieous choice and i know no one who did
no take it.
An additional Member in the Warband is far better than a simple Bonus on Spells.
So i would thin the following would be better:
Temple: add: all models gain +1 on their Survival rolls after the game
Crypt: add: your warband may include 2 Zombies
Tower: add: your warbad may include an additional Construct
Brewery:add: you gain a +1 Bonus on the spell brew potion
no ides what to add to the others.....
maybe an additional animal companion ?
your opinion ?
