The Brine Revolver in Abyssus is a precision-focused weapon designed for players who thrive on accuracy. Unlike forgiving, spread-based options like the Engine Rifle or Tesla Gun, the Brine Revolver rewards pinpoint aim with devastating single-shot damage. In the hands of a skilled marksman, this revolver can shred bosses, elites, and weak-spot enemies in just a few well-placed shots.

This guide explains how to unlock the Brine Revolver, how its mechanics work, and the best builds to maximize its raw potential.

Brine Revolver
The Brine Revolver isn’t available from the start of Abyssus. To unlock it:
- Unlock all other weapons and abilities in the game, except the Engine Rifle.
- Many of these items are hidden across runs, so full exploration is key.
- After finishing the tutorial, head to the workbench on the left side of the lobby.
- You’ll find the Brine Revolver resting on a barrel nearby. Pick it up to add it to your permanent collection.
Brine Revolver Works
The Brine Revolver is a high-damage, low-capacity revolver built around precision. Every shot matters, rewarding accuracy with massive payoff.
- Ammo Capacity: 6 rounds (shared between both fire modes).
- Primary Fire – Unscoped Shots
- Fires standard revolver rounds.
- Best for close-to-mid range engagements.
- Secondary Fire – Scoped Shots
- Zooms in for long-range precision.
- Deals massive weak spot damage when aimed correctly.
Tip: Weak spots are often glowing or brightly colored on enemies. Landing headshots and crits is what makes the Brine Revolver shine in boss fights and elite encounters.
Best Brine Revolver Build
The Brine Revolver is strongest when you lean into weak-spot targeting and burst damage potential.
Recommended Fire Modes:
Slot | Type | Details | Unlock Requirement |
---|---|---|---|
Primary | Large Caliber | Increases per-shot damage; ideal for weak spot targeting against bosses and elites. | Complete an expedition with the Brine Revolver. |
Secondary | Quick Scope | Grants bonus damage if fired quickly after scoping in. Perfect for fast, precise shooters. | Kill 3 bosses with scoped weak spot hits. |
If you struggle with consistent precision, consider using the Shotgun module instead. It sacrifices accuracy for a more forgiving playstyle.
Best Ability for Brine Revolver
- Anchor
- Acts as a close-range countermeasure.
- Provides flexibility, covering the revolver’s weakness in tight encounters.
- Balances the weapon’s slow fire rate and small magazine size.
Where to Find: Anchor is located in The Gardens, hidden behind a random locked door that requires at least one key to open.
Best Aspects for Brine Revolver
Aspects vary each expedition, but the following synergize best:

Category | Slot | Details |
---|---|---|
Shadow | Primary Fire | Shadow Aspects weaken enemies and allow you to mark them for increased damage. For the Brine Revolver, maximizing damage output is crucial, making Shadow the strongest pick. |
Lightning | Secondary Fire | Chain Lightning effects counter the revolver’s slow fire rate. Since you only have six shots, Lightning ensures nearby enemies are struck after each hit, improving crowd control. |
Freeze | Ability | Freezing enemies with your Anchor prevents being swarmed and increases elite/boss damage. This synergy balances out the Brine Revolver’s slower fire rate and limited ammo. |
Best Charms for Brine Revolver
Charms are randomized each run, but these are top picks for the revolver’s playstyle:
- Hawkeye – Increases damage by 30% the farther away you are. Perfect for scoped precision sniping.
- Giant Slayer – Grants bonus damage against bosses and elites, enhancing the revolver’s role as a boss-killer weapon.
