Acid Arrow


The Acid Arrow contains a highly corrosive acid payload that explodes upon impact causing high damage to the target. This incredibly dangerous trick arrow is standard equipment for almost every genre archer. It is generally intended for use against metal targets, e.g. armor, machines, etc., and not living targets.

The most common form of Acid Arrow has the acid contained within a glass capsule inside the arrowhead. The non-reactive glass contains the acid safely. The quiver itself has a special, impact-resistant compartment to hold the arrow safely in place. It’s a difficult balance to maintain an acid arrow in ready status so that it only breaks upon being fired and not sooner.

Some arrows will contain the acid within the shaft of the arrow itself. This allows for a much greater payload, but it has definite drawbacks. It is much more dangerous to carry and handle; it’s heavier, and the less flexible, non-standard material required makes the arrow respond differently from the standard arsenal.


The acid itself is amazingly strong, capable of eating through a door or an engine block almost instantly. It can even cause damage to Iron Man’s armors. Though it is most often a nameless concoction, when it is named the acid is often cited as being nitric acid.

Reality Check

A superacid is one that is considered to be more acidic than 100% sulfuric acid. Chemists have formed many superacids, but by far the strongest is fluoroantimonic acid. Fluoroantimonic acid is over 10 thousand quadrillion times stronger than sulfuric acid.

Fluoroantimonic acid is ridiculously strong and will eat through glass and plastic. It will react explosively with water. It will certainly destroy any and all flesh it comes into contact with. There’s only one way to store it. A container must be lined in Polytetrafluoroethylene (PTFE), aka Teflon.
