Hidden Power

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.
