One thing I’ve been thinking about why I love dungeon world is how it solves the problem of Hitpoint Mountain in two ways.
One, being fiction centered, diseases and poisons can’t be solved with rest or health potion. Debilities are cleared, but not scurvy or the plague.
Two, even in combat, if you get fried by a dragon, or stepped on by a giant, your probably dead. More subtly, bleeding out and imbedded arrow points, as well as infection, are slow and insidious killers.
