With certain options enabled: stones, coal and iron are all renewable.
- Infinite mines or infinite granite mines
- Wine Economy addon
Otherwise the amount of iron and coal and stone are map dependent.
As this is an optional addon I think it is fine as it is. Leather isn't super strong. Catapults already have a 30% chance to
miss. All the armor does is give a 30% chance to not lose a soldier when the catapult does hit and +1 temp bonus health for
duels.
The Tanner requiring a saw is indicated by the Tanner job icon having a saw in it. I wanted each of the new buildings to require
a tool so that this optional chain has a real cost to use. Otherwise there's almost no circumstance you wouldn't build it. Since
you don't start with tongs you need to build an iron smelter and metalworks to even get a leatherworker.
I'm sure if people use the addon in PvP it can be determined how overpowered or underpowered it is and we can adjust it from
that.
