I think this one is very rare

I am playing Dungeon Quest for 4 years and this is the first time that I got this one very surprising that I never expect it!


when it is time to finish the Kill Cartographer Feat or Pick Up Maps Feat, you can use a Legend Map with Eternalized Set to improve your chances of getting an Eternal Challenge Map. then save the Eternal Map for the next time you try to get an Eternal Map with the Feats.

I think I’ve only gotten about 8-9 Eternal Maps.
