I thought up of an idea while building my castle walls and towers. What if you could just place some kind of item and it summons an archer/mercenary while paying a certain amount of gold?
Remember the time of Stonehearth where I think market stalls were first introduced and when you place the market stall, there’s a button where when you press it, you summon a merchant? I was thinking of the same thing but instead of a market stall, it’s a flag/banner that you can place, select and press a button and you summon an archer instead of a merchant.
I think that whenever you summon, you would have your stored gold coins subtracted. The archer shouldn’t wander too far away from it’s banner. Also, as another mechanic, you won’t be able to hire another archer from the same banner for a while.
I am not too sure if the summon banner/flag would be better if it’s craftable or only buyable from specific merchants.
