Power Band
From Pixelmon Wiki
A Power Band is a type of power item that can be given to a Pokémon. When a Pokémon holding the band defeats an opponent Pokémon, it will earn the normal EV gains from the opponent along with 8 extra Special Defense EVs. However, the Pokémon's Speed will be halved while wearing the band. When a breeding Pokémon holds a Power Band, its Special Defense IV is guaranteed to be passed to the offspring.
It can be obtained as loot from a pillager outpost, as a tier 3 or 4 Special drop, or as a possible drop from rare boss Pokémon.
