+ * So, I know what you're thinking.
+ * "Why is this a negative trait? It sounds like a positive one!"
+ * In theory, yes. Being unable to have your limbs break DOES sound like a good thing!
+ * However, that is where limb code comes into play.
+ * Normally, with highly damaged limbs, you have a RNG(X)% chance for it to be sliced off if it takes a lot of damage and the damage from the blow is over a certain threshold.
+ * Additionally, limbs have a 'maximum damage' it can reach in which it can't reach anymore. Your arm, for example, is 80 damage maximum. Head 75.
+ * Trying to hit it more won't do any more damage, just constantly roll chances (if the hitting blow is strong enough) to cut it off/gib it.
+ * With this trait, however, as soon as you reach that maximum damage, your limb IMMEDIATELY gibs. No RNG chance rolls. 'attack must be X strong to hit it off'. Nothing.
+ * Additionally, normal limbloss code has one-shot protection and prevents bullets from gibbing limbs. This makes you forfeit that protection.
