One other Pokémon on the field, selected by the trainer.

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.
