Weapons and grenades have set prefixes, but I’ve asked before regarding shields, and nobody’s been able to give me a definitive answer. Certain ones like elemental resistance prefixes [=Ground // Alkaline // Blastproof // Inflammable] are clear-cut, but not so with others. For example, a Bulletproof Booster Shield I picked up (but unfortunately didn’t keep), and these examples: http://borderlands.wikia.com/wiki/Booster_Shield/Variant_Chart
Someone told me that they’re random and part-dependent, but is that really the case?
Does the Strength relic affect Deathtrap? I’ve looked around, and cannot find one word about it.
