Ball lightnings once had the lightning bolt spell, but started out confused, so unless their confusion duration ran out before their summon duration (rare), they wouldn't actually cast it.

in old versions monsters that lived in liquids didn't actually care about which liquid, they just needed rF+++ to survive lava, so it was possible to make monster merfolk stand around in lava if they got rF+++

From (pre-Stone-Soup) version 2.10 to version 2.83, the dungeon (D) was 36 levels deep.

Before (pre-SS) version 3.40, there was a Great Swords skill separate from Long Blades. Also "amulet of resist slowing" was called "amulet of maintain speed".

The documentation on the KPROP no_rtele_into lists an example vault to avoid not-randomly-teleporting-into as lemuel's hellion isle, and of course said vault doesn't have it.

xom is one key right of zin

Before 0.14, when a monster would have been polymorphed into a coloured draconian it had a 90% chance of rerolling the polymorph target unless the player was in Zot.

1/7th of all angels in the abyss are worshippers of Xom.

place:Foo spectre for a long period of time didn't respect holiness like the other syntax requests for appropriate monsters, so it was possible to get spectral plants (which move, oddly enough)

Before 0.14, player vampires could sense blood out of LOS ("You smell fresh blood near-by."). The detection range scaled with hunger level (14 at Bloodless), at Satiated or above there was no indication how close the blood was, and detecting blood had a (very small, distance-dependent) chance of waking the player if asleep.

fun fact: when unarmed skill gave you other auxiliary attacks, nagas headbutted more than any other race, because they headbutt when they would roll a kick

You could once help remove a net from allied monsters that have been net trapped

all chaos brand effects are weight 10 except for ensnare, which is weight 2

// Not a single habitable place left on the level. Possible in a Zig // or if a paranoid player covers a small Trove with summons. mpr("There is some commotion, and a hidden mimic gets squished!"); if (item) destroy_item(*item, true);

blue devils, iron devils, and rotting devils are smarter than orange demons, red devils, sixfirhies, and hellwings

Fire, water and air elementals once regenerated health faster when in lava/flame clouds, water, and cloudless squares respectively.

Before 0.13, there was a cloud type called gloom which had no glyph, recoloured anything in it to purple, and dissipated faster when in a halo - as long as it was also not silenced.

Pan lords used to be able to get orc/drac slaying melee attacks if you were playing as an orc/draconian respectively.

Until 0.15, grey draconians players' tail slap would trample enemies. But! Only if player was in deep water, and the enemy was also in a water tile (though they could be flying!).

<minqmay> fun fact: if an undead or demonic monster reads a scroll of holy word, and the damage would kill it, it will get set to 1 hp instead and survive <minqmay> this is not very useful knowledge however, seeing that monsters cannot read scrolls of holy word

Curse toes are in the lich genus, though not the lich species.

When removing boots of flying, if you're wearing an evocable source of flight (like a ring), the game will automatically evoke it, instantly and for free. This is almost entirely useless.

In versions of Crawl prior to 0.6, Kikubaaqudgha was totally different: Kiku's invoked abilities, for example, were "Recall Undead Slaves," "Enslave Undead," and "Invoke Death" (summoned a reaper).

Code appearing already in version 0.1 and remaining in the source code for several versions, but never actually used, defines a monster "The Mollusc Lord." Its stats are similar to Gloorx Vloq's.

< crate> btw wielding wyrmbane also reduces the accuracy of dragon breaths against you

< minqmay> amusingly, a monster with a weapon can roll 0 damage, and a monster without one can't

If disaster area turns the tile under the orb of zot into lava the orb will move out of the way, several spaces if it has to.

In old versions, you couldn't turn into a tree (even by deliberately quaffing lignification) while standing in a harmful cloud.
