CRAFT (CHEMICALS) is an Arts & Crafts Skill for chemical engineering. Its effects are passive, though some uses can use MP. AKEMI HOMURA learned this skill on Loop 2 from the stolen skillbook My Little Lab At Home, and on Loop 3 from an unspecified purchased skillbook.
Homura currently has CRAFT (CHEMICALS) at an UNSKILLED level, and has not used any recipe slots. She is currently limited in ability to use it due to lacking a FUME HOOD.
Passive: Items sell for 20% of components’ value. 10 MP reduces DC by 1.
