The Quest for El Dorado: Heroes & Hexes includes three new double-sided terrain tiles that add a new element to the game: curses. When a player stops on a demon space, they must draw and reveal a curse token to see how they're affected. Maybe they have to discard certain cards before they can travel on a particular type of terrain, or perhaps other explorers will move while the cursed one is paralyzed, or maybe you'll be afflicted by a demon, specifically a demon card that's shuffled into your deck and does nothing but frustrate you or get transformed into a half-coin each time you see it.

Why would you travel to a demonic location when bad things would happen to you? Moving to that space doesn't cost a card, so you might just be being cheap, but additionally, some demon spaces have tunnels that allow you to move directly from one hex on a tile to another on that same tile. Is that free movement worth the punishment you might suffer? The expansion includes two blockades that bear a demon symbol, and if you're the first to break such a blockade on your quest across the map, you must suffer the curse that follows.

The expansion includes six suggested map set-ups — all at medium or hard levels, and all with three new terrain tiles — as well as guidelines for how to create maps yourself.

This is an expansion. It requires  to play.
