I need some random encounters. I am running a campaign for approximately four players, and they like to be kept busy, as any players do. I need ideas for random encounters that are not simply combat, though they may involve combat. They can be for any environment or location (swamp/road/tavern/inside a castle...).
Examples:
-A disfigured man steps into the road and challenges the party to a duel, which the party would clearly win, and makes a really high bet. the players talk it over, and if they agree they discover he was disguised.
-A man runs up to the party screaming for help very frantically. All the party can make out is "explosion," and then he rips off his coat and you see a ticking clock on a powerful-looking alchemical bomb strapped to his chest.
I just need short not-all-combat encounter ideas.
Thanks in advance!
