So I wrote down this walkthrough for Epic Battle Fantasy, which turned into more of a monster guide. Take note that the HP and damage are all approximations which I think are fairly accurate. I just assumed the HP and damage would increase by 140% from normal to epic and I believe that´s a good assumption, but I have not tested it properly yet.
Also, the damage is the MAXIMUM damage the enemy will do. So you know you are in danger when your HP is below that number.
I hope this will be useful to all you people who are having trouble with the game.
Tips
-What to buy in the shop?
Waters of Life, Ethers, Potions
-What not to waste money on?
Bob-omb, Magic and Attack Potions, Antidotes
-How to prevent dying from the Spiritbomb?
I haven´t figured it out yet. My theory is by healing your characters up to max and raising your magic defence, but this is unproven.
