How do random weapon bonuses work in Torn, and do they apply when attacking NPCs?

Weapon bonuses are extra proc effects that only certain weapon types can carry, and they come in Yellow, Orange and Red tiers. The wiki's 2023 capture documents one NPC exception: Execute does not work against NPC accounts. It lists no other NPC exceptions, but nothing in the pack confirms that the other bonuses do work on NPCs.

How bonuses work

The wiki's bonus list (captured 2023-09-27) gives each bonus the weapon types that can carry it and a value range. Fury (CL, PI, SL) is a 10 - 34% chance of hitting twice in a single turn^[1]. Rage (CL, PI, SL) is a 4 - 15% chance of hitting 2-8 times in a single turn^[2].

• Stun (CL, HA, RF, SG): 10 - 40% chance to make the opponent miss next turn^[2]
• Puncture (MG, PI, RF): 20 - 51% chance of ignoring armor^[2]
• Quicken (PS, SL, SM): 50 - 219% increased Speed while using the weapon^[2]
• Specialist (MG, PS, RF, SM): 20 - 59% increased damage, but the weapon is limited to a single clip^[2]
• Proc rules (2023 wiki, plus player reports): bonuses that need a hit do not proc on a zero-damage hit, and a player reports they cannot proc on a miss. Weapon-bonus status effects last 5 minutes.

Tiers and origin

The 2023 wiki lists three classes: Yellow/Superior, Orange/Epic and Red/Legendary. Higher tiers have larger ranges; Stun, for example, is 10-15 / 16-23 / 30-40. Ranked war rewards and special caches give weapons with at least one bonus. Unique bonuses are tied to one specific weapon and only come as Superior. Exact tier odds are unconfirmed; Chedburn described a small chance of Orange and a tiny chance of Red.

Bonuses are separate procs from a weapon's base Damage and Accuracy.

Do they work on NPCs?

The wiki's 2023 capture notes that Execute does not work against NPC accounts and lists no other NPC exceptions. That is a finding from 2023, so it may have changed.

The wiki calls its general bonus list a work in progress, with 53 general bonuses. Check the current wiki bonus page before relying on any bonus against an NPC.
