DURF

OSR/PbtA‑inspired • d20 tests with advantage • 3–5 + GM • Low prep • Rules‑lite • 2–3h sessions Theme and Setting DURF aims squarely at dungeon‑fantasy: hazardous delves, strange magic, and meaningful resource choices. It embraces the OSR ethos—player ingenuity over character build depth—so tone leans more perilous than heroic, with quick consequences and room for emergent worldbuilding.

Theme and Setting

Resolution centers on d20 tests with a simple advantage/disadvantage toggle. Characters are classless; backgrounds and gear define roles.

How Play Feels

Hit Dice are low and damage is punchy, keeping fights tense. Procedures for inventory, exploration, and rests are lightweight, reducing bookkeeping without losing the crawl loop.

What Makes It Distinct

Compared to bulkier retroclones, DURF strips to essentials while keeping familiar OSR procedures. Its advantage mechanic smooths adjudication and speeds table calls, and the text is hack‑friendly under CC‑BY—encouraging tables to mod, bolt on options, or re‑skin for different subgenres.
