Hidden Power

Effect

Power and type depend upon user’s IVs. Power can range from 30 to 70.

Inflicts regular damage. Power and type are determined by the user’s IVs. Power is given by `x * 40 / 63 + 30`. `x` is obtained by arranging bit 1 from the IV for each of Special Defense, Special Attack, Speed, Defense, Attack, and HP in that order. (Bit 1 is 1 if the IV is of the form `4n + 2` or `4n + 3`. `x` is then 64 * Special Defense IV bit 1, plus 32 * Special Attack IV bit 1, etc.) Power is always between 30 and 70, inclusive. Average power is 49.5. Type is given by `y * 15 / 63`, where `y` is similar to `x` above, except constructed from bit 0. (Bit 0 is 1 if the IV is odd.) The result is looked up in the following table. Value | Type ----: | -------- 0 | Fighting 1 | Flying 2 | Poison 3 | Ground 4 | Rock 5 | Bug 6 | Ghost 7 | Steel 8 | Fire 9 | Water 10 | Grass 11 | Electric 12 | Psychic 13 | Ice 14 | Dragon 15 | Dark This move thus cannot be Normal. Most other types have an equal 1/16 chance to be selected, given random IVs. However, due to the flooring used here, Bug, Fighting, and Grass appear 5/64 of the time, and Dark only 1/64 of the time.
