What it is about
One sheet of paper, one pencil, and 1d6: that’s everything you need to play Morvanthir.
The entire game fits on one side of an A4 sheet, with artwork on the back.
After printing, ideally on paper at least 120 gsm, just cut it out and fold it into a tri-fold brochure that can also stand upright like a small GM screen.
Morvanthir is a game designed to deliver fast, satisfying dungeon-crawl sessions, either solo or with a group of friends.
Thanks to its simple yet well-structured rules, you can also play Morvanthir with a Game Master, improvising dungeon crawls or running more complex adventures.
⛊ The hero assigns three numbers to three attributes, chooses a race that grants a skill, and enters the dungeon.
Inside, each randomly generated room may contain:
???? A Trap to detect and disarm;
????️ Doors to pick or break down (but the noise will attract more creatures);
⚔️ Enemies to defeat and sometimes recruit into the party;
???? An Altar that heals wounds and teaches a skill.
♛ At the end of the dungeon, the hero may increase one attribute, then begin a new run; stronger than before and, if lucky, with new allies in the group.
Combat uses roll-under 1d6 checks, with critical hits, advantage and disadvantage, and various weapon configurations.
Formation: party members can choose to take the vanguard or the rearguard: those in front protect the others, who can attack only with ranged attacks and spells.
The 18 distinct skills are learnable and droppable, up to a maximum of three at a time, and can aid in combat, exploration, and wound recovery. They include combat maneuvers, spells, and utility abilities.
In addition to Morvanthir’s double-sided file, a PDF of printable sheets for the players is included.
