Star Upgrades

Stars are upgrades that can be applied to certain items to give them stat boosts.

Mechanics
Stars are applied to items through Essence Crafting at a Blacksmith (Malik, Igor, or Alwin). They require certain Essence, items, and/or to be added to items. The amount of resources required increases as more Stars are added. Items that can be upgraded with Stars are listed in the Essence Guide.

Master Stars
Up to 5 Master Stars can be applied to Dungeon items in an Anvil, to give them of their stats per Star while in Master Mode Dungeons.

Crimson Isle Items
Most of Crimson Isle items can have Stars applied to them, and gain of their Stats per Star. They usually require Crimson Essence and additional items to be upgraded. Varying amounts of Stars, from 2-15, can be applied to Crimson Isle Items, depending on the item.
