How this is worked out

4 steps
  1. Level term = floor(2 x 100 / 5) + 2 = 42
  2. Base damage = floor(floor(42 x 100 x 300 / 200) / 50) + 2 = 128
  3. The damage roll multiplies by 85% to 100%, then STAB x1.5, type x2, burn x1.
  4. Damage ranges from 324 to 384, averaging 353.38.

Its 5 worked examples are re-run on every release, last on 15 September 2026. What changed

Bulbapedia: Stat - Generation III onward formulas
HP = floor((2B + IV + floor(EV/4)) x L/100) + L + 10; other stats add 5 and apply the nature factor.
Bulbapedia: Damage - Generation V onward
Damage = (floor(floor((floor(2L/5)+2) x Power x A/D)/50) + 2) x Targets x Weather x Critical x random x STAB x Type x Burn x other.
Bulbapedia: Type chart (Generation VI onward)
The 18-type effectiveness matrix used for both the matchup and coverage modes.
Bulbapedia: Hidden Power - Calculation
Type = floor((a + 2b + 4c + 8d + 16e + 32f) x 15/63) from the low bit of each IV; power uses the second bit with x40/63 + 30.
Bulbapedia: Catch rate - Generation III/IV
a = (3HPmax - 2HPcur)/(3HPmax) x rate x ball x status; b = 1048560/(16711680/a)^(1/4); p = (b/65535)^4.
