2. Narrow the pool with the sidebar filters:
3. Hit Randomize. You get a quest and a weapon class, plus any challenges that rolled. Arena quests give you one of the quest's five loaner sets instead, since that's what you fight in.

An unofficial, non-commercial quest randomizer for Monster Hunter 4 Ultimate — it rolls a quest and a weapon for when you can't decide what to hunt. Not affiliated with, endorsed by, or supported by Capcom.
Every quest — its name, star, locale, objective and monsters — and every Arena loaner set is read from the game's own quest files, and the monster, quest and weapon icons and the Guild Card backgrounds are the game's own (the collaboration backgrounds' marks belong to their owners). Everything was extracted from a personally owned copy of the game; no game files are redistributed. Downloadable Event and Challenge Quests aren't on the cartridge, so they aren't in the pool, and Guild Quests are built by the game at run time, so they aren't either. The monster classes in the Monsters filter are assigned by hand, under the game's own class names.
Monster Hunter 4 Ultimate and all of its names, data and icons are © CAPCOM CO., LTD. The UI textures and the MHFU font are shared with the same author's MHGU fan apps, and the app itself is a port of the MH3U Quest Randomizer, itself a port of the MHGU Quest Randomizer.
