The exact materials to upgrade a gear piece from any tier and star to any higher one — and the attack, defense and power you gain. Real numbers from our verified dataset, not estimates.
Every figure comes from our open, sourced gear.json dataset (cross-checked & verified). Spot a wrong number? Tell us — it gets fixed for everyone. How we verify →
The gear ladder behind this calculator — 58 steps from Green to Red T6 3★, ending at 4,104,000 power and +171% stat bonus — was rebuilt in June 2026 after a cross-check found real defects exactly where a spender climbs: placeholder power values across steps 36–49, missing Red T5/T6 tiers, and a 1,000-off typo at step 27. The rebuilt dataset was checked against multiple sources: two independent databases agree exactly on the full ladder including Red T3–T6, an older third source stops at Red T4 with the previous-patch bonus rate, and one value was verified directly in-game (Red T2 = +117.50%). Every step now carries a confidence score shown in the tool: 99/100 for steps 0–41 (three sources plus in-game), 91 for Red T3–T4, 87 for the newest Red T5–T6 tiers.
