You can't clear thousands of dungeons without making a few Frenemies... so that's what we did! As long as your Imaginary Frenemies are safely stored inside their blister, they help you in combat - but if you release them to get at the cards inside, you can't use their rule anymore. Oh, temptation! Gives you a bonus in your Munchkin game as long as it remains unopened! Gives you a bonus when you open the package! Gives you special cards once you open it that are better for you than anyone else!
