New build

Plan class, skills, stats and gear in one place. The link in your address bar is the build — copy it to share, or save it to your library.

How far each value has been checked is shown as a badge on the formula behind it — from verified in-game down to our own estimate. Gear staging and the damage numbers are the least settled. Spotted something off? Feedback is very welcome. Formulas & sources →

Max HP

i

Max HPUnknown

floor((floor(base_hp * (1 + vit / 100)) + gear_hp) * (1 + bonus_hp_percent / 100))= floor((floor(40 * (1 + 1 / 100)) + 0) * (1 + 0 / 100)) = 40

Maximum HP: the class base value for the level (from the HP curve), increased by 1% per point of VIT, plus flat HP bonuses from gear, then multiplied by percentage Max-HP bonuses.

Curve trust varies by class (spec §12.10/§12.11). Acolyte: fitted to 13 measured status windows, every measurement matched within 1 HP, extrapolation confirmed at the level cap. Thief: the ×0.79 transfer was checked against a clean level-up pair and holds within 1 HP, while plain renewal would need negative gear HP there. Other first classes (Swordsman, Mage, Archer, Merchant, Novice): the same ×0.79, but untested for them. Everything else: unmeasured renewal placeholder known to run ~20-25% too high. The staging (VIT multiplier, flat gear HP, then MaxHP%) is verified independently of the curve.

Max SP

i

Max SPUnknown

floor((floor(base_sp * (1 + int / 100)) + gear_sp) * (1 + bonus_sp_percent / 100))= floor((floor(14 * (1 + 1 / 100)) + 0) * (1 + 0 / 100)) = 14

Maximum SP: the class base value for the level (from the SP curve), increased by 1% per point of INT, plus flat SP bonuses from gear, then multiplied by percentage Max-SP bonuses.

Curve trust varies by class (spec §12.10/§12.11). Acolyte: fitted to 13 measured status windows, every SP measurement matched exactly — its SP curve is a shape change (higher start, flatter slope), not a scaling. Thief: measured to match plain renewal SP exactly, which is why the Acolyte fit is deliberately NOT transferred to other classes. Other classes: renewal, unmeasured.

HP Regeneration

i

HP RegenerationOur estimateUnknown

max(1, floor(max_hp / 200))

Natural HP regeneration per tick (~6s standing): a two-hundredth of Max HP, at least 1.

Sources disagree: rAthena adds a fifth of VIT on top, the TW calculator does not. The TW variant is used here; an in-game measurement settles it.

SP Regeneration

i

SP RegenerationUnknown

floor(int / 6) + floor(max_sp / 100) + 1 + (int >= 120 ? floor((int - 120) / 2) + 4 : 0)= floor(1 / 6) + floor(max_sp / 100) + 1 + (1 >= 120 ? floor((1 - 120) / 2) + 4 : 0) = 1

Natural SP regeneration per tick (8s standing, 4s sitting): a sixth of INT plus a hundredth of Max SP plus 1. From 120 INT (reachable with gear) a jump bonus is added.

Cast Variable Cast Time × 0.92 · Fixed Cast Time × 1

Variable Cast Time ×

i

Variable Cast Time ×Unknown

max(0, (1 - sqrt((2 * dex + int) / 530)) * (1 + bonus_cast_time_variable_percent / 100))= max(0, (1 - sqrt((2 * 1 + 1) / 530)) * (1 + 0 / 100)) = 0.9

Factor on the variable cast time of all skills: the more 2×DEX+INT, the shorter; from 530 the variable part is 0 (instant). Gear "Variable Casting Time -X%" lines shrink the factor further. The fixed cast time portion (~20%) is reduced separately.

Fixed Cast Time ×

i

Fixed Cast Time ×Unknown

max(0, 1 + bonus_cast_time_fixed_percent / 100)= max(0, 1 + 0 / 100) = 1

Factor on the fixed cast time portion: gear lines like "Fixed Casting -5%" multiply it down; without such gear it stays at 1.
