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.

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.

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 only, along with +10% in both Master and normal mode. They take experience levels to apply.

Trivia

 * Especially as they're just being released, its recommended to only apply Master Stars to high level weapons and armor such as a refined version of Necron's Blade. If you have the money, the first star isn't too expensive compared to the second, third, and fourth, so it may be worth while to buy some for your gear.
