33% to spawn on any unboxed weapon of legendary rarity. Can pay 15k to spawn a “prefixinator” that will have a 66% chance to assign your weapon with a prefix. Some examples of prefixes would be: Quickswapping - decreases your weapons swap speed, Reserve - allows your weapon to spawn with full ammo reserves at the beginning of every round and Lightweight - increases your movement speed and jump height by 5% when the weapon is held out. Stattrak could spawn as a prefix if that is implemented at some point. In my opinion, the prefixes shouldn’t directly increase the dps of the weapon.
When the weapon is in your inventory it would appear as “Quickswapping Maximus” or “Reserve Corrupted Nobel” and once you renamed it would appear as “(name) (Lightweight P90)”.
Tell me if you think it’s a shit idea or a good one.
