The inscription gump for Spell Plague is incorrect according to documentation. Galic is not needed. Demon Bone is required according to uo.com. I also missed needing Sulfurous Ash. This causes the client to complain not enough regs. However, all the regs in the client are satisfied.. https://uo.com/wiki/ultima-online-wiki/skills/mysticism/ ps. I created the scoll... but also have a box of all the regs missing dragon blood and demon bone.. so I missed the extra regs needed..
