Boss: Life on the edge

You are the ruler of the Cursed Swamps of Ardia.
Your cozy fortress was once a quiet place, but in recent times a swarm of Heroes from all over the Kingdom shows up at your door. You are living on the edge, work is stressful but you're showing up every day to save money for retirement.
Earn enough gems and follow your dream!

Hints:

• You can select one or more attacks and items from the menus. They will be used during the battle
• Attacks that cost more deal more damage
• You can select only one arena setup at a time
• Inspect the opponent's weapon and item with the mouse to find their stengths and weaknesses
• The higher the opponent level, the more dangerous they are. Plan your strategy accordingly
• Try to spend as little as possible on each battle in order to maximize profits
• Stress goes up after each battle, but losing stresses you out more than winning
