Explosives

Explosives is a subskill of Alchemy that focuses on the creation and use of volatile mixtures designed to release destructive force. This includes bombs, flash devices, concussive charges, and unstable compounds that can be weaponized in combat or used to manipulate the battlefield. Those skilled in Explosives understand not only how to create devastation, but how to control it—turning raw alchemical power into precise tools of destruction.

Each rank in Explosives grants a +1 bonus to Alchemy checks when creating, modifying, or safely handling explosive or volatile substances. This bonus applies when crafting damaging alchemical items, increasing their stability, or repurposing them for controlled effects such as breaching, distraction, or area denial. Additionally, there are Alchemical Recipes that require a specific rank in Explosives.
