ProjectE Klein Stars

Klein Stars are portable EMC batteries. Six tiers - Ein, Zwei, Drei, Vier, Sphere, Omega - each holding double the EMC of the tier below, up to millions of EMC in the Omega star.

• Charging. Charge them in an Anti-Matter Relay (or on the Transmutation Table interface).
• Spending. Powered tools, armor abilities, rings and amulets draw from a Klein Star in your inventory instead of burning fuel items.
• Upgrading. Four stars of one tier combine into one star of the next tier, keeping their stored EMC.
