I know many secrets...
Henzell says...
  1. A level 5 conjuration/poison spell - it is a penetrating punch of pure poisonous power. Please perceive that pests partially protected from poison (as opposed to prohibitively protected; includes most living and demonic creatures) will proceed to procure piddling punishment. To-hit:8+power/20. Removed as a player spell in 0.25.
  2. Piss-poor, prefer Poison Arrow.
