The First Descendanthas many different progression systems that aren’t thoroughly explained in-game.

One example is Weapon Proficiency, a leveling system for every weapon in the game.

How it works, its benefits, and ways to increase your Weapon Proficiency are never explained.

Increase your FPS, fix awkward keybinds, and more with this in-depth prefs guide.

This guide aims to address that.

But before we start, let’s explain what Weapon Proficiency is and how it relates to Mastery Rank.

What Is Weapon Proficiency?

Weapon Proficiency isnotthe same as weapon level.

Weapon level affects base damage and caps out at Level 100.

Additionally, you have the ability to install Crystallization Catalysts on any weapon at Weapon Proficiency 40.

We cover this process more in the “Weapon Proficiency Bonuses” section.

If you reset a gun’s Weapon Proficiency, leveling it again willnotgrant Mastery Rank progress.

Once again, Weapon Proficiency caps out at Level 40 for all weapons.

Weapon Proficiency Boosters

Weapon Proficiency boosters increase all Weapon Proficiency gains by 30%.

This doesnotdouble-dip with a standard XP booster.

Here’s how to take down Pyromaniac, a flame-spitting nightmare of a boss in The First Descendant.

You’ll need to level a new weapon to further your MR rank.

Starting module capacity is determined by your current Mastery Rank.

The higher it is, the more capacity you’ll have to start with.

This bonus doesnotstack with Weapon Proficiency but rather takes the place of Weapon Proficiency at earlier levels.

Once your Weapon Proficiency bonus exceeds your MR bonus, you’ll begin to see module capacity gains.

That sounds more confusing than it is, so let’s give an example.

If you’re MR7, you’ll have a starting module capacity of 38.

You’ll need to use Energy Activators or Sub modules (Descendants only) to gain additional capacity.

This is required to fit the strongest, most expensive modules into your builds.

For endgame min-maxing, Crystallization Catalysts are essential.

Viessa is arguably the strongest starting character in The First Descendant.
