Under normal circumstances, players can only carry one transport cart at most. After learning the sub-skill "Transport Cart," which is part of the Advanced Logistics Skill, they can carry additional carts depending on the level of their Logistics Skill—three more with Advanced Logistics and a total of five with Master-level Logistics. This means a player can typically carry six carts via their skills. These six carts can accompany the player in campaigns across different regions. If the player's Vice Hero also masters Logistics, they can carry another six carts.
Then there's the Merchant License. The higher its level, the more transport carts a player can hire from the Chamber of Commerce. However, the additional carts hired from the Chamber of Commerce can only travel on a few fixed trade routes and will not follow the player into battle.
