Promethean Spark (Bot Fuel)

The Promethean Spark is the fuel that keeps your Daedalus Construct mining bot running.

Each blaze-powder spark powers one bot for one hour. Click a spark into the Construct's GUI to feed it, and stockpile a few if you want it churning through the Mines while you're away.

Where to get it: a common loot drop across the server's reward sources — keep an eye on crates and boxes and the usual bosses and caravan hauls.
