Etherfields: 5th Player Expansion allows you to add a 5th player.
This is not only a 5th player expansion, but also an additional character to choose from for any other player count game. This character archetype is called Reaper.
This archetype will be based on wounds that this character has taken - the more, the better combos she will be able to execute. There will be multiple ways of using this to your advantage - either by full-on risky play or perhaps more focused on balance and getting a good healing deck build. The Reaper will provide quite interesting mechanics for the whole team!
