I find one in a lock chest in a cave, one in a lock chest burried (treasure map) and one on a fire elemental.
I traveled on all the map and there is no more caves or houses.
I loot no more treasure maps apparently.
So I have to search for aberrant creatures. What are they ? How do they spawn ?
For the higher-level creatures same question how do they spawn ? Do i have to meet specifics requirements ? Will they spawn only in a specific place in the map or they can spawn anywhere ?
