Nuclei in TUSG.io
All 10 nucleus items compared — stats shown at power level 10.
The nucleus slot is your constitution: maximum HP boosts, radiation resistance and physical damage resistance. It decides how much punishment your build absorbs before skills even matter.
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.
