Here's a guide. Please keep it alive. 1. You get cards as your hero levels up, 10 per hero, but some heroes get the same cards. 2. Grullborg Grimtooth, the Green Orc hero, has the highest max mana at 3500. Each hero is different. 3. You unlock Cave of Trials after beating the game once, and starting a New Game Plus. 4. In COT5, there is an invisible goblin that does 999999 damage. You aren't supposed to kill him, you keep him back with Mermaid water shots while the rest of your troops kill the castle. Hope people bother to read this. 5. It's probably a good idea to complete the conquest as all the characters before attempting to beat the COTs
