The Plasmasword is a melee weapon added by the Royalty DLC that does a decent amount of damage, has a medium cooldown, and deals sharp damage with the bonus of frequently setting the opponent on fire.


Plasmaswords cannot be crafted, instead they can only be purchased from Outlander and Empire combat suppliers and faction bases, or recieved as a quest reward.

They can also be obtained from the following raider types:

Raider Kind Chance Average Quality Health
Champion ?% ? 70-230%
Nobles (All) ?% Excellent 100%


Plasmaswords perform largely the same as any other melee weapon, with one primary difference. When performing the Cut and Stab attacks, a successful strike has a 50% chance to do an extra 10 Flame damage. As with all Flame damage, this damage has no AP and if it successfully damages the target, there is a chance to set them on fire.

Despite being an incendiary weapon, pyromaniac pawns equipped with plasmaswords will not have the +5 Pyromaniac has incendiary weapon mood buff they receive from using molotov cocktails or incendiary launchers. It is currently unknown whether this is intended behavior, or a bug.


The plasmasword will often set enemies on fire. Enemies on fire will run around wildly and are unable to fight back. This makes the plasmasword dominant in a 1v1 fight, or in any melee fight out in the open. However, the fire can end up being a major drawback. Enemies on fire will ignore collision, meaning that they will run right past a melee block, end up behind your colonists, attack from the back, and ruin your formation.

Mechanoids are completely immune to fire or heat, so other ultratech weapons or even a plasteel longsword are superior in those situations. In addition, outlanders and pirates will often carry firefoam pop packs. Firefoam packs will activate when its user is set on fire, immediately extinguishing them. Any pawn inside the leftover firefoam is immune to ignition.

If you have the option, buying any of the other ultratech melee weapons tends to be more generally useful.
