Mastery Rank Guide: The First Descendant's Account Progression

Mastery Rank is the progression system that follows your account, not your characters. It gates your mod capacity, it grants permanent bonuses, and it is the reason two players with the same Descendant can have different power ceilings.

It is also the system new players misunderstand most — because it cannot be farmed directly. This guide covers how it works and what it actually does.

What Mastery Rank is

Account-wide. Every character on your account benefits. Level it once, and every Descendant you ever unlock starts stronger.

Separate from Descendant level. Your character level caps at the current level; Mastery Rank keeps climbing past it. They are different tracks.

The mod capacity link. This is the important part. Your capacity — the budget that limits which modules you can equip — is partly determined by Mastery Rank. Higher Mastery Rank means more capacity, which means stronger builds with the same mods.

How it levels

From normal play. Mastery XP comes from the content you run — missions, operations, the endgame modes. There is no dedicated Mastery farm.

The implication: the fastest way to level Mastery Rank is to play the content that pays the most XP per minute. Which means the same content that levels your characters and weapons also feeds Mastery.

The compounding effect: because it comes from all play, the players with high Mastery Rank are simply the players who have played efficiently for longer. There is no shortcut — but there is a wrong way, which is covered below.

What the bonuses do

Mod capacity. The main gate. Every Mastery level adds capacity, and capacity is what lets you equip the modules your build needs.

Permanent account bonuses. Each rank grants account-wide stat bonuses that apply to every Descendant. Small per level, significant over dozens of levels.

The endgame link. The hardest content assumes a certain capacity level. Players who reach it with low Mastery Rank find their builds do not fit — and the fix is playing, not farming.

The efficient path

Do not farm Mastery directly. There is no such thing as a Mastery farm. Run the content that levels your characters — the XP feeds both.

The weekly operations. The best XP-per-hour in the game, which makes them the best Mastery-per-hour too. Weeklies are the answer to almost every progression question in this game.

The endgame modes. Onslaught and the Mega Dungeon pay the most XP per run. Once you can run them, they are your Mastery engine.

The boosters. The XP boosters the game hands out apply to the same content. Use them on reset day.

The traps

Wasting XP on content below your level. The XP scales with the content. Running old missions for “easy” XP is the slowest path there is.

Spreading across too many characters. Mastery comes from play, but your capacity is spent per-character. Level one character’s build properly before starting the next.

Ignoring the weekly. Every skipped week is a week of Mastery XP gone. The weekly is the single largest source.

Buying Mastery boosts. The shop sells progression boosters. They work, and they are the definition of optional — the game is fully playable without spending a cent, and the boosters only shorten the same content.

The realistic timeline

Early game: Mastery climbs naturally from the story.

Mid game: The weekly operations become the engine. This is where most players’ Mastery Rank lives.

Endgame: Onslaught and the Mega Dungeon runs feed it continuously, and the capacity they unlock is what makes the hardest builds possible.

The players with the highest Mastery Rank are not the ones who ground the hardest in one week — they are the ones who did their weeklies, every week, for months.

The one thing to remember

Mastery Rank cannot be farmed, only fed. Play the content that levels your characters, do the weekly operations, and the rank climbs on its own. The capacity it unlocks is what lets your builds fit — and there is no shortcut past it, only the slow way and the wasted way.
