Overcharge Crystal

The Overcharge Crystal is a single-use consumable that supercharges your next booster.

Keep one in your hotbar and it works automatically: the next booster you activate has its duration doubled, and the crystal is consumed in the process. It works with any personal or global booster, so you can line it up before a big mining or XP window to stretch the buff twice as far.

Where to get it: an uncommon drop from bosses.
