Trained Only
This skill allows you to mix chemicals to create acids, bases, explosives, and poisonous substances.
Acids and Bases: Acids are corrosives substances. Bases neutralize acids but do not deal damage. A base of a certain type counteracts an acid of the same type or a less potent type.
The statistics given on the chart represent an end result of 4 “uses” of the compound.
Type of Acid | Purchase DC | Craft DC Acid | Craft DC Base | Time |
Medium (1d6/1d10)* | 8 | 15 | 10 | 1 min |
Potent (2d6/2d10)* | 12 | 20 | 15 | 30 min |
Concentrated (3d6/3d10)* | 16 | 30 | 20 | 1 hr |
Explosives: Building an explosive from scratch is dangerous. If the Craft (chemical) check fails, the raw materials are wasted. If the check fails by 5 or more, the explosive compound detonates as it is being made, dealing half of its intended damage to the builder and anyone else in the burst radius.
Type of Scratch-Built Explosive | Purchase DC | Craft DC | Time |
Improvised (1d6/5feet)* | 6 | 10 | 1 round |
Simple (2d6/5 feet)* | 12 | 15 | 10 min |
Moderate (4d6/10 feet)* | 16 | 20 | 1 hr |
Complex (6d6/15 feet)* | 20 | 25 | 3 hr |
Powerful (8d6/20 feet)* | 25 | 30 | 12 hr |
Devastating (10d6/25 feet) | 30 | 35 | 24 hr |
If the check succeeds, the final product is a solid material, about the size of a brick. An explosive compound does not include a fuse or detonator. Connecting a fuse or detonator requires a Demolitions check.
Poisonous Substances: Solid poisons (such as arsenic) are usually ingested. Liquid poisons (such as scorpion venom) are most effective when injected directly into the bloodstream. Gaseous poisons (such as cyanogen) must be inhaled to be effective. The table illustrates the characteristics of various poisons.

Special: A character without a chemical kit takes a -4 penalty on Craft (Chemical) checks.
A character with the Builder feat gets a +2 bonus on all Craft (Chemical) checks.
