Calculation used

damage

Worked out from Bulbapedia: Stat - Generation III onward formulas and 5 other sources.

The cartridge games round each modifier with their own half-up rule, so a single point of difference against an in-game roll is expected.

How this is worked out

4 steps

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