So far I have only played the game with my wife. I play the Overlord and she plays the Champions. One thing we noticed is getting a useful treasure piece hard to come by and its not like there is an over abundance of money and chest laying around. So we have been play testing with two new sets of rules.
1st set:
We pull Items here two champions will not be able to use out. This does not include stuff she doesnt like but just non champion related weapons.
2nd:
Once and only once she can purchase an item of her choice from a chest color all ready discovered. Now this requires going to town and trading in at least 1 said treasure for 1/2 its amount.
So far the second seems the most reasonable. Well thats it let me know what you think.
