In Dungeons and Fighters games, game challenges and upgrades should be a problem that bothers many players. Many players are not sure what the four-to-one means. In fact, they buy four sets and finally open one set. .
1. To open one out of four, buy four sets of mentor equipment, then wait until level 52 to sell three sets and unlock the last set.
2. However, it should be noted that the remaining set cannot be synthesized into a sky suit immediately and can only be upgraded slowly.
3. The tutor set will also have a chance to issue a graduation badge, but the probability is small.
4. The four purchased suits will also receive graduation-level platinum titles, which can increase combat effectiveness.
