The Chosen Ones

Just played on Normal now and I find little difference in the difficulty of the game as compared to easy. I suggest that other than increasing enemy units' damage, you can or you may already:

- Increase hp, hp regen, attack speed, armor of enemy units
- Decrease gold and exp gained from killing enemy units
- Increase cost of buying items and recipes and books from stores
- Increase damage and frequency of bosses' spells, mini-events and events
- Add more spells, mini-events and events for bosses
- If something requires a time limit like fighting epic boss chapter 3, shorten the time
- More demanding quests and more quests
- More mini-bosses and enemy units

I like the gold and exp thing.

Easy: -10% Exp & Gold
Normal: -20% Exp & Gold
Hard: -30% Exp & Gold
Extreme: -40% Exp & Gold
****: -50% Exp & Gold
