The Plasma Sword in Derelict on Roblox is an anomaly within the one-handed blade class. Unlike traditional standard swords that favor rapid swings at standard melee distances, the Plasma Sword trades raw attack frequency for an extended reach of 10 and built-in elemental Melt buildup. It stands as a specialized drop obtainable only through specific combat encounters.
This weapon appears during early tutorial segments, but keeping or farming a permanent version requires hunting down specific mid-to-late game enemies. Understanding where it drops, how its modifiers scale, and which Weapon Arts interact with it will help you decide if it fits your build.
How to Get the Plasma Sword in Derelict
The Plasma Sword is classified as a Special Weapon drop tied directly to high-threat hostile units.
- Elite Avarus Soldiers: According to the official game wiki, the Plasma Sword has a 70% drop chance when defeating an Elite Avarus Soldier. In player video guides, players target Fort Occo (Fort Ch), ascending the mountain area to hunt down Avarus Soldier spawns until a glowing red elite version appears.
- Ambush Events: The weapon can also drop from random Avarus Soldier ambush events as separate loot, though the specific drop rate for ambushes is not confirmed in available documentation.
Other plasma equipment drops from neighboring factions: the Plasma Shield drops from red elite shield-bearers in the Delta Lab (observed by players around an 80% drop rate), while the Plasma Dagger drops from elite dagger wielders.
Plasma Sword Base Stats and Unique Properties
In player weapon tier rankings from Super Cheats and Gamezebo, the Plasma Sword is positioned in the B-Tier due to its slower handling relative to other one-handed swords. However, its baseline power matches higher-tier late-game alternatives.
| Stat Metric | Baseline Value | Class Comparison |
|---|---|---|
| Weapon Category | Special Weapon / Sword | One-handed melee |
| Base Power | +44 | Matches Aureatus & Crimson Swords |
| Armor and DEF Bonus | +10% | Standard for sword class |
| Stamina Bonus | +20 | Standard for sword class |
| Attack Speed | 1.0 | Slower than standard swords (1.2) |
| Attack Range | 10 | Longer than standard swords (8) |
| Passive Debuff | 25 Melt | Exclusive elemental trait |
Community wiki notes point out that while the Plasma Sword is officially tagged as a sword, its reduced speed and lengthened reach make it operate similarly to a lightweight greatsword without occupying greatsword scaling.
Upgrades and Forging Progression
Upgrades for the Plasma Sword require Crowns and Forging Stones, which are processed at an anvil or forging station such as the one found at Gideon's Camp.
| Grade Level | Power Scaling | Upgrade Cost (Crowns) | Upgrade Cost (Forging Stones) | Cumulative Crowns | Cumulative Stones | | --- | --- | --- | --- | --- | | G-0 | 130.0% | 0 | 0 | 0 | 0 | | G-1 | 136.5% | 249 | 7 | 249 | 7 |
Note: Upgrade figures beyond Grade 1 have not been fully cataloged in available reference tables.
Weapon Arts and Combat Integration
Weapon Arts require Soul points and stamina to execute. According to the Derelict Official Wiki and player testing, the Plasma Sword has its own signature art alongside universal sword abilities.
- Plasma Cutter (Signature Art): Costs 24 Soul and 20 Stamina with a 6-second cooldown. It launches a slow-moving plasma projectile slice that deals 70% Power damage per second, inflicts Melt, and slows targets. Players frequently combo this with mobility or locking spells such as Umbral Claws to guarantee projectile connection in PvP.
- Rapid Slash: Costs 5 Soul and 30 Stamina with a 5-second cooldown. Delivers two rapid slashes dealing 130% and 120% Power damage.
- Swirling Strikes: Costs 5 Soul and 30 Stamina with a 4-second cooldown. Spins around to strike twice for 70% and 140% Power damage.
Players can equip Weapon Arts in the Abilities menu at any discovered Bonsai checkpoint. If an offhand ability (such as a shield skill) is equipped at the same time as a mainhand weapon art, the game prioritizes the offhand ability by default. Unequip the offhand art if you wish to use Plasma Cutter or other blade skills.
Frequently Asked Questions
Can you keep the Plasma Sword from the tutorial?
No. In the updated starter sequence, your character briefly handles a plasma weapon during the facility breakout, but it is stripped away after the scripted encounter with the commander before arriving at the crash crater.
Which enemies drop the Plasma Sword?
It drops exclusively from Avarus Soldiers that spawn as glowing red elites, primarily farmed by community members around the mountainous fortifications of Fort Occo, as well as during sudden soldier ambush encounters.
What does the Melt status effect do on the Plasma Sword?
Every basic attack applies 25 Melt buildup onto the target, working in tandem with the slowing and multi-hit properties of its Plasma Cutter weapon art.
