Nanon: (tier-based)% chance to dismember upon penetration.

The nanon mod can be applied to most beam weapons. It adds a tier-based chance to dismember limbs whenever a projectile from the weapon penetrates a target. The exact percentage chance to dismember is randomly determined when the mod is applied, and will either be equal to the weapon tier, or the weapon tier + 1. This randomization is not tied to a stable seed, meaning that it can be re-rolled using Precognition or similar effects.[1]

Nanon weapons are not affected by the Dismember or Decapitate skills. They will always have a very small chance to decapitate, regardless of these skills. Each time that the nanon dismember effect triggers, there is a 1 in 1,000 chance (0.1%) that decapitatable limbs, namely heads, will be added to the pool of limbs that the projectile can randomly dismember. Even then, the decapitatable limb must be randomly selected from among all of the target's remaining dismemberable and decapitatable limbs.[1]

Item and Mod Interactions

Nanon weapons that are also overloaded will have their chance to dismember increased by an additional 2%.[1] Wearing precision nanon fingers will increase the overall chance to dismember threefold. The overall formula for these interactions is:

( NanonDismemberChance + OverloadedBonus ) × PrecisionNanonFingersBonus
