Version 0.31: This article is up to date for the latest stable release of Dungeon Crawl Stone Soup.

The Alchemy school focuses on inflicting poison and altering your surroundings. Despite its name, no Alchemy spells affect items in any way. It is the combination of the Poison Magic and Transmutations schools.

  • Many Alchemy spells can be considered as "side" spells. They often have a major limitation, but come with strong/useful effects to compensate.
    • For example, Irradiate has only 1 range, and can only be used a few times in a row safely, but can otherwise tear apart enemies. Most of the poison-themed spells do little against foes with poison resistance, but are great against foes without.
    • There's no Alchemy spell above level 6, but spells like Irradiate, Yara's Violent Unravelling, and Eringya's Noxious Bog are useful for the entire 3-rune game.
  • Most of Alchemist's starting spells are strong, but don't do much against foes with poison resistance. Sticky Flame can be used to take out rPois monsters, though as a level 4 spell, it'll take a while to use consistently.
