Money and resources are vital for upgrades. Here's how to maximize your gains:

- Renovate Buildings: In New York and other settlements, renovating buildings (taverns, shops, banks) provides a steady income stream over time. Prioritize these early.
- Capture Gang Strongholds: Liberating these areas not only reduces Assassin influence but also provides a one-time cash reward and increases your income.
- Naval Convoys & Forts: Regularly engage in naval activities. Convoys yield significant cargo (metal, wood, cloth), and capturing forts provides large sums of money and unlocks new trade routes.
- Hunting & Selling: Hunt animals, especially legendary ones, and sell their hides and bones to general stores.
- Looting: Always loot fallen enemies and treasure chests. Every little bit adds up.
- Warehouse Raids: These mini-missions involve infiltrating a warehouse and stealing its contents, providing valuable resources.
A balanced approach to these activities will ensure you always have enough funds and materials for all your crafting and upgrading needs.
