# Biomes and Oxy relationship

Oxy parts always belong to a biome. And depending on the rarity of the piece, it will get a boost in that biome and consequently also from the **combination of the biomes that compose it**. It should be noted that for each biome there will be three variants of each particular piece. One for **mobility**, one for **attack** and one for **defense**.
