A very dangerous plant which fends off predators by spraying corrosive vitriol at them. Even experienced adventurers give oklob plants a wide berth.

“Carbonic acid is one of the three materials which together form the starting point of vegetable growth; the others being water and nitric acid. This acid is formed of carbon and oxygen in the proportion of one part of the former to two of the latter chemically combined. It is a colorless gas, having an acid taste and smell; is soluble in water; weighs one-half more than air and can be poured from one vessel to another, as a liquid may be; 100 parts of water dissolve 106 parts of this gas, and it is from this source that the roots of plants derive the needed supplies of it.”
-Henry Stuart, _The Culture of Farm Crops: A Manual of the Science of
Agriculture, and a Hand-book of Practice for American Farmers_, ch X. 1887.

Useful Info

Oklob plants are vicious plants that spit acid at you from a distance. Not only will this take a large chunk out of your health, but it can also corrode you. Fortunately, oklob plants do not move and cannot pursue you if you flee. They are most often found in the Lair, but they can appear in various vaults elsewhere.

In addition to turning all existing oklob plants neutral, worshipers of Fedhas Madash may use Grow Oklob ability to summon an allied oklob plant that will spit acid more often and will be summoned for longer with increasing Invocations. Another Fedhas' ability, Overgrow, sometimes produces oklobs or oklob saplings when turning dungeon walls into allied plants.

Tips & Tricks

  • Like most things in Crawl, if you aren't prepared to deal with them, you can usually stay away, and fight them later. It's rare for oklobs to be guarding something vital, and even then, you can go to Dungeon or Orc.
The game automatically travel-excludes tiles in range of an oklob, so it's hard to get hurt unless you're actively taking them on.
The exclusion zone won't take into account any plants in the way, so it can be tricky to determine their "real" line of fire.
  • If you absolutely need to destroy a group of oklob plants, it's best done slowly and carefully. It can't go anywhere, so there's no need to hurry. It's often best to clear the rest of the floor before taking it on; fighting something while heavily corroded isn't a good idea.
    • Ranged attackers should fight at the edge of line of sight. If things get too hairy, you can go out of sight, allowing you to regenerate. This can be combined with an amulet of regeneration to eventually take it out. Don't let multiple oklobs fire you at once, since 2+ acid bolts can kill most characters in Lair.
    • Summons can waylay an oklob plant while you hang back. Command them to attack it using the 't' key, though you must keep the plant in your line of sight (preferably from behind a plant or summoned meatshield).
    • You can use invisibility to avoid attracting their attention or to allow you sneak up on them. This significantly reduces their ability to hit you with acid, but they do still occasionally get lucky.
    • Oklobs don't have much willpower, so Hexes or hex wands can easily disable a plant. A wand of polymorph can create thorn hunters and shambling mangroves, so it might not be wise to polymorph.
  • For Fedhas worshippers, oklobs are powerful allies. The corrosion status is very useful; inflicting -8 AC is a strong effect in practice. The oklobs themselves deal good damage, too. Plants under Fedhas can fire through each other.


  • Prior to 0.28, Spit Acid had 3d7 base damage, but dealt an extra "acid splash" (4d5 damage on players, 2d4 damage on monsters). Also, oklobs created by Fedhas fired more often.
