Obscure Talents

Obscure Talents are a type of item which can be only equipped by Corrupted mythics that have been ranked up, starting from rank 1. These elusive objects improve your monsters' abilities in unexpected ways that can really help their strategy when combined with their skills.

Every time a monster goes from rank 0 to rank 1, they’ll automatically earn an entry-level Obscure Talent. If you want to get the highest-level Obscure Talents, you’ll need to complete the Era Saga dungeons. Obscure Talents level up automatically depending on the rank of the monster who carries them.
