Cores in TUSG.io

Cores govern your mass economy — how fast you gain it, how slowly you decay it, and how well you shrug off radiation. The stat sheet nobody screenshots and every big player swears by.

Every wearable drops with a power level from 1 to 10; its stats scale linearly with power, so a power-5 item gives exactly half the values below. Higher-level monsters and boss kills roll better power.
