I just released a small rules supplement for RUNE called Duet. I've had people asking for a two-player mode of RUNE for a long time, and now the rules are here! You and a friend will each create your own Engraved and explore Obron together. You'll find rules for exploration, combat difficulty modifiers, and four new items to use in character creation designed to support duet play.

Enjoy!
