3 STAR (low rank) mark a milestone in the player progression

Upon completing 3 star rank in the village you will unlock the urgent (rampage and bishaten after). Before progressing further I strongly suggest to pause your progression and start thinking on what you have now. Most of the weapon requires elemental damage to work properly, however not every weapon have access to those kind of sets.
Following here there is a updated list for all 14 weapons. Keep in mind those are physical builds.
