Stat effects
Pokémon have six different types of IVs, one for each of the six stats (HP, Attack, Defense, Special Attack, Special Defense, Speed), with values ranging from 0 to 31 in each. Each IV increases the respective stat by IV x Level / 100, with a Level 100 Pokémon having a total boost in stats equal to their IVs. The pattern of IVs also determines the type for the move Hidden Power.
