Total Combat Tactics Players are often faced with a choice between fishing for low cost units and leveling up.
Dedicating your resources to developing units and taking control of the board is sometimes the best course of action. But deciding when to level up and when to roll isn’t always straightforward. Without the numbers, it could be mere guesswork.
