Guide: What is Weapon Proficiency in The First Descendant (Quick Breakdown)

After grinding three consecutive Void Intercept runs with my new legendary sniper last week, I noticed its base damage jumped 12% even though I hadn’t installed any new reactor mods or upgraded its rarity. I dug through the game’s hidden menus to find the cause, and that’s where I stumbled on the answer to what is weapon proficiency the first descendant players keep asking about. This under-explained mechanic is one of the easiest ways to boost your overall combat power without spending rare upgrade materials, and far too many new players sleep on its benefits entirely. You don’t have to grind for hours to unlock its full potential either, once you understand how it works, you can level it up passively while you play through normal content.

What Exactly Is Weapon Proficiency in The First Descendant?

At its core, weapon proficiency is a hidden permanent progression system tied to every individual weapon in your account’s collection. It works separately from mod upgrades, rarity enhancements, and character skill bonuses, so its effects stack with every other damage boost you have active. Every time you deal damage with a weapon, you earn a small amount of proficiency for that specific gun, and as you level it up, you unlock permanent stat boosts for that weapon. Weapon proficiency is tracked per individual weapon, not per weapon type or per character, so even if you have two identical legendary assault rifles, their proficiency progress is completely separate.

Common and rare weapons cap out at proficiency level 10, while epic and legendary weapons go up to level 15. Each level grants a 1.2% increase to the weapon’s base damage, so a maxed legendary weapon gets a 20% flat base damage boost on top of all other upgrades. Higher rarity weapons also unlock extra bonus stats at max proficiency, like extra critical hit chance, faster reload speed, or reduced recoil. You only gain proficiency for the weapon you are actively holding when you deal damage, so if you swap to a sidearm to finish off a low-health mob, that damage won’t count towards your primary weapon’s progress.

How to Level Up Weapon Proficiency Fast

The amount of proficiency you gain is directly tied to the amount of damage you deal, so the faster you can output consistent damage, the faster you’ll level up your weapon. You don’t have to play high-difficulty content to earn proficiency faster either, as the gain rate is the same across all mission tiers. But you don’t have to grind 10 hours a day to max a weapon’s proficiency, either. I leveled my legendary shotgun from 0 to 15 in just three days of casual play, following these simple tips:

  • Run low-difficulty Void Chasm missions with the weapon you want to level, as hordes of weak mobs let you deal consistent high damage fast
  • Equip AoE damage mods on your weapon to hit multiple targets at once, as each target hit counts towards your proficiency gain
  • Save your daily Void Intercept boss runs for the weapon you’re currently leveling, as boss damage grants 3x more proficiency than standard mob damage
  • Avoid switching weapons mid-mission unless you’re leveling multiple weapons at once, as only the active weapon gets credit for damage dealt

You don’t lose proficiency progress if you swap weapons or stop using a gun for a few weeks, so you can pause leveling a weapon to try out a new drop and pick back up right where you left off later. Proficiency gains are not affected by mission difficulty, so you can grind low-level content just as fast as endgame runs, which is perfect for new players who haven’t unlocked harder content yet.

Core Benefits of Maxing Weapon Proficiency

The biggest and most obvious benefit of maxing weapon proficiency is the permanent damage boost it gives to the weapon itself. That 20% base damage increase makes a massive difference in endgame content, where even a 5% damage boost can cut down boss kill times by several minutes. Max weapon proficiency adds a permanent 20% base damage boost to the weapon, which stacks with all mod, reactor, and character skill bonuses, so it multiplies all your other upgrades instead of being a flat minor add-on.

Beyond individual weapon boosts, you also unlock account-wide series bonuses when you max out all weapons in a specific category. For example, if you max all 7 assault rifles currently in the game, you get a 2% permanent assault rifle damage boost that applies to every character on your account, and every future assault rifle you unlock. Cross-series proficiency bonuses apply to every character on your account, even if you never use the original weapons you leveled, so it’s worth maxing even lower rarity weapons if you’re working towards a category bonus.

The only real downside to weapon proficiency is that you can’t transfer progress between two weapons of the same type. If you find a better version of your favorite assault rifle, you’ll have to start its proficiency grind from scratch. That means it’s smart to focus on weapons you plan to use for at least a few weeks, instead of wasting time on guns you’ll replace in a day.

Common Weapon Proficiency Mistakes to Avoid

One of the most common mistakes new players make is swapping weapons every time they get a new drop, which means none of their weapons ever reach max proficiency. Even if you get a slightly better weapon, it’s often worth sticking with your current one until you max its proficiency, because the 20% damage boost will make it stronger than the new drop until you level the new one up. You can always swap over later once you have a few maxed weapons to fall back on.

Another mistake players make is thinking they have to keep a weapon in their inventory to keep the proficiency bonus. You don’t need to keep a weapon in your inventory after maxing its proficiency to keep the bonus, so you can scrap or sell it for materials once you’re done with it, and the stat boosts will still apply if you unlock the same weapon again later. That’s especially useful for low-rarity weapons you only used early in the game, as you can scrap them for materials once maxed without losing any benefits.

Many players also ignore low-rarity weapons entirely when it comes to proficiency, assuming they’re not worth the effort. Proficiency works on all rarity tiers of weapons, so even common early-game guns are worth leveling if you use them regularly. Maxing a common assault rifle only takes a couple of hours, and it counts towards the category-wide assault rifle damage boost that will apply to all your future legendary assault rifles too. It’s a low-effort way to get permanent account-wide boosts without spending any rare materials.

Now that you understand what is weapon proficiency the first descendant players have been confused by, you can start incorporating it into your regular play routine to boost your combat power for free. It’s one of the most low-effort, high-reward mechanics in the game, and even leveling a few of your most-used weapons to max will make a noticeable difference in how fast you can clear endgame content. You don’t have to set aside special grind sessions for it either, just pick one weapon to focus on each week, and you’ll unlock its full benefits before you know it.
