Primordial Guardian bosses always scale to be two levels higher than your current level. It's recommended to enter vaults after obtaining powerful weapon upgrades or unlocking key passive skills.
Complete the first vault around level 15 to benefit early from Glide Pack upgrades. Approach subsequent vaults as soon as you reach their respective regions and acquire the necessary Vault Keys.
