there is an enemy I just fought called "toadstump". The enemy fights by givng the player 4 poison whenever it is hit. The only thing it does with its cards is it can apply the "anemic" effect which makes poisoning stronger but doesn't deal damage on its own. I accidentally figured out that due to the sudden death rule, where after a battle goes on for a while attacks become 30% stronger every round, you can easily win this fight by ending your turn over and over until sudden death builds up enough for you to be able to one-shot the enemy.
I just won a daily challenge with 99% difficulty rating. I love when a game as in depth as this can actually make you feel that you're somewhat decent at it.
A few suggestions from a new player (up to 3 white dragons):
1. Make the summon spell only summon in an unoccupied tile. Once, the mage tried to summon a scorpion on top of a pit and multiple times have the the mages tried to summon an enemy on top of another enemy.
2. I just got to try out the dwarf for free and I think you should be able to choose between using a charge attack or using your bow. A lot of the time, it makes more sense to use the bow instead of the charging attack (keeping enemies out of melee range, having a good bow but a bad sword, staying out of the way of exploding gas spores, etc.)
Other than these couple complaints, I am really enjoying this game and can't wait until fame level 50!
