Where is this gear now?

Equipment level Orange stars Filled sections Red forge level

Equipment level is the “Lv.” number on the item. It matters because red forging scales existing stats; Power Cores add promotion stats and eventually unlock higher enhancement caps.

Why should I trust this answer?

Known numbers first. Community rules second.

FL2 uses the published cost and stat tables for every Core section and Forge step. It then applies the community pattern: spread cheap Core promotions, use the strong Forge path through +2 when the item has enough base stats, and avoid deep forging too early.

No made-up future power. Last Z’s Promote screen shows the next stats and material cost, but not the item’s total power after purchase. This calculator will not ask you for a number the game does not show or pretend it can calculate an unpublished power formula.
