How does weapon stats work?

[Arcanix]

is the weapon stats will remain the same even when you upgrade the weapon power?

[Ixamesh]

Yes, power level doesn't affect gear stats, it's basically a damage dealt/taken modifier.

Stats should also be compared within the archetype, e.g. Precision SMG vs Precision SMG, not Precision vs Aggressive or SMG vs Auto

[Emurinus]

Power just exists as a gatekeeping device that gives +/- to damage given/received. Whether your weapon is 1600 or 1810, it'll have the same normal stats.

At most, your weapon's power will affect its damage output against enemies below/at/above your overall power (ex. a 1600 power weapon is a pea shooter against 1700 enemies, but a 1800 weapon will hit them fairly hard).
