Builds / Plasma Launcher
Best Plasma Launcher Build in Abyssus
Fires explosive plasma orbs that detonate on impact. Scales hard with area damage, extra projectiles, explosion bonuses and control — when the build comes together it deletes rooms faster than almost anything.
Best for: Spawner rooms & dense packs (weak vs single bosses)
Recommended Plasma Launcher build
Community-tested Plasma + Anchor setup: AoE-on-distance mods plus bounce make explosions cover half the room, so you fire from a corner. The Anchor's freeze plugs the launcher's weak single-target damage.
⚑ Best Aspect
Frozen (Frost) — or Windburst
✦ Key Blessings
- Frost to freeze packs, then bonus damage to frozen
- Windburst for extra explosions
⚒ Ancient Forge mods
- Flack Cannon
- Void Infusion
- AoE-based-on-distance + bounce
◈ Recommended Charms
- Fan amulet & "Mr Boom" amulet (AoE-based-on-distance)
- Giant Slayer for bosses
➤ Ability
Anchor (triple-shot freeze) — bonus damage to frozen boosts boss DPS
Pros / Cons
- ✔ Best-in-class room clear
- ✔ Massive AoE ceiling
- ✔ Forgiving aim (splash)
- ✘ Poor raw single-target boss damage
- ✘ Setup-dependent
- ✘ Self-damage up close
Depth 30 variant
Its weakness is boss single-target — bring the Anchor freeze + bonus-to-frozen so you still have boss damage at Depth 30.

Plasma Launcher Ancient Forge upgrades
Weapon-specific Forge mods that reshape how the Plasma Launcher plays.
- Seismic Fuel — Hitting 3 enemies increases the explosion radius for 5 sec.
- Molotov Fuel — Enemies take 50% continuous weapon damage for 5 sec. after being hit.
- Revolving Valve — Lasting attacks have doubled duration, charged attacks have halved buildup.
- Explosive Valve — Damage now scales with the projectile's explosion radius.
- Accelerating Core — Explosions increase in size the further the projectile travels. Up to 100%.
- Bouncy Core — Projectiles bounce 2 times or until an enemy is directly hit, exploding each bounce and dealing 25% more damage.
- Spreading Heat — Hitting an enemy suffering from status effects or that are Stunned, Slowed or Frozen deals the same damage to a nearby enemy.
- Repeating Blasts — Plasma Launcher explosions have a 60% chance of triggering again. Additional explosions can also trigger again, but have a 20% decreased chance per explosion.
