If you thought your builds in The First Descendant were locked in, think again. Season 3: Breakthrough introduces a new system that genuinely changes everything — Trigger Modules. These aren’t just another stat boost or filler mod. These things reshape your entire playstyle, from the ground up.
In this guide, I’ll walk you through:
- What Trigger Modules are and how they work
- How to unlock the slot for each Descendant
- The full material grind
- The best farming strategy (including drop rates & boss tips)
- How to start strong and avoid common mistakes
Let’s jump right in.
The First Descendant Trigger Module Farming Guide 2025
What Are Trigger Modules & Why Do They Matter
Trigger Modules are the headline feature of Season 3 — special, golden-tier mods that directly modify your Descendant’s skills or weapons, creating entirely new interactions.
We’re not talking simple stat buffs. These modules add real mechanics — like:
- Missed shots stacking debuffs that nuke bosses when you land one
- Reloads that explode into AoE blasts
- DOTs that pull enemies into black holes
- Or MP gaps that ramp up skill damage
There are 9 Trigger Modules at launch:
- 7 for skills
- 2 for weapons
These aren’t tied to power creep — they’re tied to playstyle diversity. A tanky Ajax can become a room-clearing monster. A poison-heavy Freyna can now map-wide melt waves of enemies. They’re the kind of thing that finally breaks the meta-wide mold.
How to Unlock the Trigger Module Slot for Each Descendant
Before you can use a trigger module, you’ll need to unlock a golden slot on each character. It’s a one-time grind per Descendant, and here’s exactly what’s needed:
Step-by-step Unlock:
- Go to Prime Hands Console in Albion.
- Select Unlock Arcade Trigger.
- Complete these requirements:
- Proficiency Level 40 for the Descendant
- Arcade Tuning at level 40
- Activate your Energy Activator
- Use Crystallization Catalyst 10x (for socket expansions)
- Craft a Refined Axiom Crystal at Annias
That crystal is the final step, and the real grind starts there.
Refined Axiom Crystal – Materials Required
Crafting a Refined Axiom Crystal requires 4 rare materials from Axiom Planes:
- Entropium
- Celentra
- Kerasid
- Breach Stone Shards
You can get small amounts from supply/resource caches, but drop rates are stingy. If you want to speed things up, you’ll want to farm bosses and missions.
Best Method – Boss Farming
- Final Bosses in Axiom missions drop 15–20 of each resource.
- Focus on missions with short clear times for fast repeat runs.
- Expect ~7 missions per crystal, depending on luck.
Pro Tip:
Entropium is the most used and most demanded. Nail’s research alone needs 300, so expect this to be your main bottleneck.
Best Trigger Module Farm – Operational Areas & Wall Crasher
Once you’ve unlocked your slot, it’s time to actually start farming for Trigger Modules.
Here’s what you need to know:
Trigger Module Drop Rates
- Found in Axiom Planes missions
- Every mission has a 25% chance to drop a Trigger Module Spoils Box
- You can hold up to 100 modules and break extras for resources
The Best Farm: Wall Crasher Boss
- Spawns once per hour
- Guaranteed 4 Trigger Modules per kill
- Drops other high-tier loot
- Easily the best farm if you’re online during the spawn
Operational Areas
- These rotate on a timer and take 7–10 minutes to clear
- Good chance at:
- Trigger Modules
- Materials for Refined Axiom Crystal
- Blueprints and Research Mats
Basically, these are the all-in-one farm. Do them regularly and you’ll passively gather both materials and a variety of trigger modules.
Trigger Module Quality – Stats, Rarities & Rerolls
Each Trigger Module has:
- A fixed effect tied to a skill type (e.g., clash, projectile, AoE)
- Random stats like:
- Proc chance
- Bonus multiplier
- Cooldown bonuses
You can’t target-farm a specific module — it’s random.
They come in Blue, Purple, and Gold rarities, visible by color dots on the module icon.
What Makes a Good Module?
- Higher rarity = better potential stats
- Gold + perfect rolls can boost DPS by 20–30%
- Farming duplicates is necessary if you want god rolls
Currently, there’s no system to craft or re-roll stats, but the devs are planning to add trading in future updates — think trading card-style economy.
How to Pick the Right Module for Your Descendant
Every Trigger Module is tagged by skill type — clash, projectile, AoE, etc.
To Equip:
- Open your inventory > trigger modules
- Pick a module matching one of your skills
- Hovering over a module shows which skill it affects
Suggested Descendants to Focus First:
- Enzo, Ultimate Bunny, Frayna, Serena, Nail
Why? These characters have kits that scale extremely well with Trigger Modules and benefit most from early unlocks.
Efficiency Tips for Farming
- Add trigger mods to your Library > Consumables > Misc tab to spotlight drops
- Run in public matches to shave off 20–30% of mission time
- Don’t fixate on perfect rolls early — stack quantity first, sort quality later
- Combine your mod grind with your research farming to save time
Trigger Modules are more than just a shiny new toy — they’re a core system that finally opens up real build diversity in The First Descendant. Whether you’re trying to solo hard intercepts or break free from cookie-cutter metas, this is the system to dive into.
So get that Axiom crystal done, target your farming around Wall Crasher and Operational Areas, and start experimenting. The grind is real — but so is the payoff.
