Master Star

Master Stars are items which upgrade 5-star Dungeon items with Master Stars, increasing their stats within Master Mode. They are obtained from Catacombs Master Floors 3-6. It is expected that the fifth star will be released with Master Mode floor 7.

Obtaining
Master Stars are rare drops from Dungeon Reward Chests in Catacombs Master Floors 3-6. The floor they drop in is 2 higher than the tier of star it is. The odds of dropping a master star in Master Mode are very little. The 4th Floor has the smallest odds for its difficulty. 1 in 25 for a second master star. You drop these master stars in either an obsidian or bedrock chest.

Usage
Master Stars can be used in anvils with Dungeon items to change their stars to Master Stars, which appear as red stars at the end of the item's name. Each Master Star grants +5% stats of that item in Master Mode. They take experience levels to apply.
