An additional full playset of core set Ranger cards.

The Ranger Card Doubler exists for players who want to double-up on their card sets (aspect cards personality cards specialties and backgrounds). For example if you want to play a campaign with two Rangers who have the same background or two who have the same specialty or even the same role you'll need to pick up the Ranger Card Doubler.

It's also good for groups of 3 to 4 players if--as that third and fourth player--you'd like more options than whatever the first two players haven't chosen. It's by no means necessary however. The core set fully supports up to 4 players.
