Suggest to make sorta "seashore market" which only allowed to build on near-sea area. This building serve as trade channel for purchasing mercenary troop / general with either token or guild coin. The variety of mercenary include all villain we encounter in various adventure. How do we access to purchase these mercs depend on the adventures we cleared. Building limit only 1 and max limit for market holding these merc troops is 1000, for merc gens is 5. Player allowed to retain or release these troops or generals. Release them ( troop/ general) will not refund.
