Every bonfire gives you a boost up if you have a hangglider.
But hang glider can only carry 5 pounds or you fall to your death. So you gotta be naked with 1 bomb or something? Mwahahaha…
Then later you can add a hanglider flying dragon dungeon and say its because the high winds so the hangglider works with any weight just only in the dungeon.
Maybe add a floating castle that players can only get to in the world by flying on updrafts naked only to the castle in the clouds
