Munchkin [NL]

You start as a level one human with no class. But as the game progresses you can transform into a dwarf, elf, priest, mage and thief. This is Munchkin, a card game that is the ultimate parody of Dungeons & Dragons. Fight monsters, conquer treasure and also take treasure from your teammates. Anything to get to level ten and win the game is allowed.

Kick open the door and see what's there: is it a monster or an object? If there is a monster in the room you can choose to fight him. But be sure that you can defeat him, otherwise you will have to flee. If you can defeat him you will get his treasure and rise one level. If you cannot defeat him you can call your fellow players for help. But of course they help for a reason and may ask you to share the treasure. You can also hinder each other by throwing potions, involve other monsters in the fight or make the monster he is fighting stronger. Almost anything goes in Munchkin, as long as you make sure you win.
The player who reaches level ten first, wins the game.
