Replace the estimate with live in-game costs before committing resources.

DECISION RULE

Finish one primary before funding alternatives.

Use the calculator to identify a resource gap, then compare the target weapon in the DPS Calculator. A level increase is valuable only when its damage gain changes future runs.

// FAQ

Upgrade Calculator FAQ

How much does it cost to upgrade a weapon?

Select the weapon, current level, and target level to see the current MVP estimate. Exact costs are not yet verified official values and will be replaced as player-submitted level data is confirmed.

When is a weapon upgrade worth it?

An upgrade is strongest when it completes a meaningful level breakpoint for the primary weapon. Avoid spreading limited coins and medals across several unfinished weapons.

How is farming time estimated?

The MVP model divides the required coin gap by a placeholder 4,500 coins per run and applies a 0.32-hour cycle. Replace this with the account’s real income for a personal estimate.
