How does the calculation for scenario level differ in solo mode compared to multiplayer, and how does this affect monster stats and rewards?

Multiplayer (Recommended Difficulty):
- The scenario level is calculated as the average level of all characters, divided by 2, rounded up.
- Example: If all characters are level 2, the average is 2. Divide by 2 (result: 1), so scenario level is 1.
Solo Mode:
- The scenario level is calculated differently to increase difficulty:
  - Take the average level of all characters in the scenario.
  - Add 1 to this average.
  - Divide by 2 and round up.
- Example: With three level 4 characters, the calculation is:
  - ((4 + 4 + 4) / 3) + 1 = 4 + 1 = 5
  - 5 / 2 = 2.5, rounded up = 3
  - So, scenario level is 3.
Open Information Variant:
- If playing with open information, use the same scenario level calculation as solo mode, even with multiple players.

Monster Stats:
- Monster base stats (health, attack, etc.) are set according to the scenario level.
- Higher scenario levels mean stronger monsters.
Other Effects Tied to Scenario Level:
- Gold Conversion: The number of coins on loot cards is converted to gold based on scenario level.
- Trap Damage: Trap damage increases with scenario level.
- Hazardous Terrain Damage: Increases with scenario level.
- Bonus Experience: The amount of bonus experience for completing a scenario increases with scenario level.

In solo mode (and open information variant), scenario level is calculated as (average character level + 1) / 2, rounded up, making scenarios harder than in standard multiplayer.
This higher scenario level increases monster stats, gold conversion, trap/hazardous terrain damage, and bonus experience.
