A whole Cairn Second Edition character in one throw. The seed is the character:
#s=oak-fen-317 rolls the same Kettlewright for everyone, forever.
Background, name, 3d6 attributes, starting gear packed into the ten
inventory slots, two background tables, a bond and an omen — hand a party out as a URL,
print it, or reroll and keep looking.
Kit them out, then take them to the encounter oracle — Cairn publishes no challenge rating, so that page plays the fight five thousand times instead and tells you what happens — or up the trials, eight real fights with the wounds carried between them. Or see what a slot is worth, where every relic and weapon is priced in the same currency.
