From Guild of Dungeoneering Wiki
- The higher the level of the monster you fight, the greater the reward for defeating it. Resist the temptation to always place the easiest monster cards to fight, or you won't have equipment of a high enough level to defeat that last Boss.
- Often when the game gives you a certain number of turns before the Boss will fight you, if you fight the Boss earlier than that, it will be weaker. Tooltip the boss at the start of the level and check its traits to find out.
- When a level doesn't have a time limit, you are free to expand the dungeon and fight lower level monsters to build up your strength slowly. There's no need to go straight for the boss or treasure.
- On levels where a boss chases you, putting down a monster directly in front of them will slow them down.
