Gem

Trunk-only: This article pertains to a feature of Crawl which is being tested. It will likely change before the next release, and may even be removed entirely.

A stone of unearthly beauty and almost immeasurable value outside the dungeon. Within its confines, it is utterly useless. Zot hoards these gems jealously, and will spitefully smash them soon after an adventurer enters the branch of the Dungeon in which they rest. Still, a very quick-moving adventurer might seize one first and keep its precious shards. Zot cannot track gems outside their home branches, so with truly astonishing speed, it might be possible to abscond with one still intact... but such a feat is difficult to credit, and likely pointless besides. Once the Orb of Zot is taken, Zot will be unable to smash any gems.

Gems are treasure items found at the end of most branches, which do nothing but add to your score. They expire after a certain amount of time spent in the branch.

Useful Info

Each found gem adds 100,000 points to your score (10,000 points for non-winning games). They have no other purpose. They do not take up inventory space.

Each gem has its own timer. Like the Zot clock, the timer ticks down as you spend time in the gem's corresponding dungeon branch. After it runs out, Zot destroys the gem. If the gem hasn't been found yet, it is permanently lost.

If the gem is found, the timer continues to run. On expiry, the gem is shattered, but you still keep the score bonus.

The length of the gem timer depends on the branch where it originates from:

Branch	Gem Time (decaAut)
Dungeon	6000
Lair	7500
Snake Pit / Spider's Nest	6000
Shoals / Swamp	4500
Slime Pits	1200
Elven Halls	6000
Vaults	7500
Crypt	6000
Tomb	6000
Depths	7500
Realm of Zot	2000

Strategy

Main article: Speedrun

Gems are purely for bragging rights; if you only care about winning, don't bother.

That being said, if your goal is to collect all the gems, you basically need to turn count speedrun. See that page for more tips.

List of Gems

• Smoky gem (The Dungeon): 6,000 turns

Swirls of dark smoke seem to lurk in the depths of this gem. Countless dark deeds were done in the Dungeon even before Zot seized and remade it, and their dreadful residue now taints every hint of beauty trapped within its confines.

• Shimmering gem (Elven Halls): 6,000 turns

Unearthly energies gently flow along the surface of this gem, guided by the archmage who first built the Elven Halls. Countless generations of elves flocked to learn from her, but her foremost pursuit was always the perfection of this piece of art.

• Earthy gem (The Lair): 7,500 turns

Deep within this gem, flowing leaves and swaying branches seem to lurk. And here, a bone picked clean - there, a predator's eyes, staring hungrily out..?

• Mossy gem (The Swamp): 4,500 turns

Though it drips with mud and muck, still a peculiar dignity attaches itself to this gem. The people of the Swamp, who first carried this stone, struggled against insurmountable odds. They failed, but there is much to admire even in the ruin of their efforts.

• Azure gem (The Shoals): 4,500 turns

As clear and blue as a cloudless sky or a depthless sea, this gem holds its secrets locked within impenetrable depths.

• Jade gem (Snake Pit): 6,000 turns

Sigils of fire burn deep within this gem, symbol of the eternal compact between naga and salamander. Their bond is that of the poison which scourges the impure and the flame which burns away impurity.

• Milky-white gem (Spider's Nest): 6,000 turns

Smooth as a spider's silk, white as the eyes of some crawling thing which has lived too long in the dark, this gem buzzes with a fearful potential. Still, to a certain eye, it possesses a strange allure...

• Starry gem (The Slime Pits): 1,200 turns

Odd lights twinkle within the depths of this gem. From what strange stuff is it made, and from what distant land did it travel?

• Shining gem (The Vaults): 7,500 turns

Many are the treasures of the Ironbound Order, but none older nor more precious than this steel-shining gem. The Vaults were first forged to hold it, and none who gazed within its depths could fault the choice.

• Ivory gem (The Crypt): 6,000 turns

Countless spirits swirl around this gem, shrouding it in a bone-deep chill. Unwelcome in the Good gods' afterlife, they find here a heaven of their own.

• Sanguine gem (The Tomb): 6,000 turns

They who smote down Death herself and buried themselves in a Tomb of their own making were not shy of their ambitions. Fain to seize upon baubles and overweening proud, their Lord journeyed into their eternal unrest with this gem upon their breast.

• Midnight gem (The Depths): 7,500 turns

The stoneborn brought forth this gem from the uttermost depths of the earth as a gift and a warning: beware Zot! That it lies now within Zot's power is a sure proof of the perversity of mortals and fate alike.

• Prismatic gem (The Realm of Zot): 2,000 turns

Shining with every colour of the rainbow and a few others besides, some consider this gem 'a bit tacky'. Preposterous!
