🔨 Forgehammer Calculator

Calculate forgehammer and mythic gear costs for gear mastery upgrades.

Parameters

Levels 1–10 require only Forgehammers.
Levels 11–20 also require Mythic Gears (1 per level above 10).

Mastery Costs

Select levels and click Calculate.

The mastery math

Gear mastery in Kingshot runs from level 1 to 20 per gear piece, and the cost curve is mercifully regular: each mastery level costs level × 10 Forgehammers, and from level 11 onward each level additionally costs (level − 10) Mythic Gears. That means a full 0 → 20 mastery on one piece totals 2,100 Forgehammers and 55 Mythic Gears — and the second half of the climb (11–20) is where almost all the Mythic Gear cost lives. The formula was documented from the kingshot.net forgehammer reference in April 2026.

Planning implications

  • Level 10 is the natural F2P parking spot: you bank the cheap hammer-only levels on every piece before any piece pays the Mythic Gear tax.
  • Because cost scales linearly with level, spreading hammers across pieces gives more total mastery levels than pushing one piece — push a single piece only when a specific stat threshold matters for your march.
  • Forgehammers also appear as a cost line in Red-quality hero gear (levels 101–200) — if you are working on both systems at once, check the Hero Gear Calculator before committing your stock.

How the forgehammer calculator works

Totals the Forge Hammers and Mythic Gears needed to take a gear piece from one Forge level to another, then multiplies by how many pieces you are doing.

Hammers for a level
hammers: level * 10 — Ten Forge Hammers per level, flat.
Mythic Gears for a level
mythic: level > 10 ? level - 10 : 0 — Nothing below level 11. From 11 upward it is level minus ten — one at 11, two at 12, and so on.
Stat bonus at a level
bonus: lv * 10 — Plus ten percent per level.
Across pieces
grandH = totalH * pieces — The per-piece bill multiplied by the number of pieces you are forging.

Maximum Forge level is 20 (FH_MAX). Those four rules are the whole model — there is no lookup table behind this one, which is why this page shows the arithmetic instead of a data table.

Every expression shown in code above is quoted from js/calc-forgehammer.js, which is the file this page actually runs.
