To protect brickwalled villages with sniper.
- every tower requires X authority to can build, so if you have 7 towers, you need at least 7xX authority
- every tower drains village-authority
- boosts dmg from ranged weapons by X
- boosts agi by X
- lowers the chance to get hit by ranged weapons when you are in one
Problem is, that you could use that in vaults. But for villageprotect it would rock.
