Potion of strong poison
|A terribly venomous potion.|
Quaffing a potion of strong poison poisons you for 3 to 15 (more) levels (with a strong probability for 9). Poison levels over 5 are very nasty, and this potion can put you anywhere from yellow poison status to pink and even to red (where it can do 100+ damage before fully running its course). This potion is so toxic that it can even partially ignore poison resistance, affecting you as though you'd just quaffed a potion of poison.
"That liquid tasted extremely nasty..."
Prior to 0.13, this potion did nothing to characters with poison resistance.
