Weapons in defiance are unique as they have their own leveling bar. How do you level a weapon in Defiance? By using it :). Each weapon has a skill bar in its icon and it fills up as you do damage with that weapon to enemy that give you experience. So if you get experience points after you kill a mob (they show as orange numbers on your screen) you are sure to level your weapon.
Once the bar on your weapon fills out you get an extra bonus on your weapon and 4 ego points. The downside is that you cannot get any more weapon skill from that weapon so you have to get a new one. The best thing is to salvage or sell the maxed out weapon a get replacement.
A question that I often get is how to level my weapon skill fast in Defiance? One of the fastest ways to boost your weapon skill is in Co-op missions which are the Defiance version of instanced group quests. there are a lot of mobs to kill and with the help of three other team mates they go down fast and you get experience quick. Here you must deal the killing blow to get the weapon experience so don’t stop shooting.
The level of experience you get from killing mobs is based on the amount of experience you get and the amount of damage that you deal. In situations where you are in a group you have to get the killing blow to get any experience. This applies to Co-ops, PVP and Arkfalls. A good tip in Arkfalls is to concentrate your fire on all enemy mobs even the small ones (except the skitterlings…don’t kill them as they weaken crystals).
Each level you gain for a specific weapon you gain a bonus stat. like faster reload, plus crit, plus melee damage and less recoil. The maximum weapon skill for each type of weapon in Defiance is 20. So to level all your different weapon types you will need to kill a lot of mobs. The BMG’s or Bio-Magnetic Guns are exceptions as you level them by healing other players. A great place for leveling BMG’s is major Arkfalls as there are usually lots of wounded players. The BMG will chain heal up to 7 players.
Leveling certain types of weapon to level 5 or 10 is also a requirement for many Combat Pursuits so be sure to check them out in the Goals menu.
