COST CALCULATOR

Upgrade Cost Calculator

Add operators to see costs broken down per step — Level·Elite (in game order: E0 max → Elite 1 → E1 max → Elite 2 → E2 max), each skill level 2–7, Mastery 1–3 per skill, and each module stage 1–3. Click a target step in a group and all preceding steps are included automatically. For a leveling step you can type the exact target level; setting it below the cap locks the next Elite promotion (drag the rail down to fill up to the cap at once). EXP is shown as an equivalent count of Senior Battle Records (2000 EXP). Click a material icon for its details.
