Rare Booster Box

The Rare Booster Box is a box that opens into a single personal booster.

Cracking it grants one random 1.5x personal booster — XP, Shard, Energy, or Ore — running for 30 minutes. Each of the four is equally likely, so it's a quick way to line up whichever multiplier suits your next half-hour, whether you're chasing levels, mining shards, Ancient Energy, or raw ore output.

Where to get it: the Fund II Lootbox, the weekly Descent Cache, and the guaranteed pool of the Tartarus Map I Crate.
