Tired of boring and borderline useful wanted posters of old? Try those new ones.
There's 18 of them in total, just as many as there are originally so you can print this and put into sleeves with original cards used as backs.
Half of them mention something called wondrous items. This is related to my other house rules so without going into detail simply treat "wondrous item" as a keyword, meaning "Draw cards from the adventure deck until you reveal a magic object. Take it and discard the rest."
Alternatively, ignore all such posters and only use those that grant just gold.
