Once upon a time, an enterprising thief and wizard created a system of portals leading into the secret treasure troves and chambers of the rich. Too scared to loot them himself, he instead charged an extortionate fee for entry to anyone who wanted to rifle through them.

The items inside such troves are likely to be useful, but beware: the wizard is long dead, and even while alive he never offered a money-back guarantee.

“He saw a large cavern and a vaulted [roof], in height equalling the stature of a full-grown man and it was hewn in the live stone and lighted up with light that came through air-holes and bullseyes in the upper surface of the rock which formed the roof. He had expected to find naught save outer gloom in this robbers' den, and he was surprised to see the whole room filled with bales of all manner stuffs, and heaped up from sole to ceiling with camel-loads of silks and brocades and embroidered cloths and mounds on mounds of vari-colored carpetings; besides which he espied coins golden and silvern without measure or account, some piled upon the ground and others bound in leathern bags and sacks. Seeing these goods and moneys in such abundance, Ali Baba determined in his mind that not during a few years only but for many generations thieves must have stored their gains and spoils in this place.”
-_The Arabian Nights_. trans. Sir Richard F. Burton, 1885.

Treasure trove portal.png A treasure trove is a small sub-branch, filled with loot specifically tailored for your character using acquirement code (usually around 16 items, though this can vary). They are usually perfectly safe, though a few possible layouts prove dangerous. Only one treasure trove can generate per game, and they are not guaranteed to appear in every game. The troves chosen are mostly random, though if a trove is entirely inappropriate for your character (e.g. a book trove for a fighter), its probability of appearing is reduced but not eliminated. Thus, fighters may occasionally end up in a book trove (where they will mostly find manuals), or unarmed fighters might rarely get a weapon trove.

Troves can only be accessed through a locked portal entrance which can generate almost anywhere. To unlock a treasure trove, you must meet its demands:

  • There is a 5% chance that it will ask for all your piety. You won't be excommunicated, but it will reset your piety as if you had just converted (about 15/200). This is never generated if you are a demigod or you worship Gozag or Uskayaw.
  • Otherwise, there is a 1/3 chance that it will ask for an item available in a shop. This will often be an artefact, but may be a high-value mundane item. Unless the item itself is incredibly useful, these troves are effectively just asking for gold.
  • Otherwise, it will ask for an item or stack of items. There are a number of possibilities, each individual item type being equally probable[1]:

For items with enchantments or charges, the values the trove asks for are minimums. Thus, a trove asking for a +4 demon whip will accept a +6 demon whip without protest. The item's ego makes no difference, and it will even accept artefacts provided they have sufficient enchantment (although the latter option may not be desirable). In the case of stacks of items, the trove will only take as many as it's asking for if you have more than the required amount. The item being given must be unequipped in order for it to be accepted; this prevents accidentally offering an item that is not intended to be given.

The cost of a trove has no bearing on the quality or type of items you will find inside. Also, unlike most portals, treasure troves are not timed and will remain active until you deal with them. Once you enter and exit one, however, it will be sealed forever.


First, remember that like other portals, you can only enter the treasure trove *once* so do not get in with a full inventory or you will have to leave stuff inside.

Much like scrolls of acquirement, a treasure trove's yield can run all the way from near-worthless to jaw-droppingly awesome. More often than not, though, it's worth opening a treasure trove if you find one. Odds are that there will be something in there you want.

When it comes to jewellery, you do have some control over what a treasure trove will generate. The code prefers to give you amulets and rings you haven't identified yet, so if there are still several items left unidentified, it may be worthwhile to go to any jewelry shops you have access to and buy any garbage items you haven't identified yet. Spending a little money on an unidentified ring of attention or amulet of inaccuracy might significantly improve your odds of getting that ring of slaying or amulet of regeneration you needed.

Treasure troves often ask for gear with a particular enchantment level. While the base type requested is non-negotiable, the enchantment level requested is the minimum that it will allow. For example, if a trove asks for a +4 demon blade, it will accept a +6 vampiric demon blade. On the other hand, if it wants +5 fire dragon scales, it won't accept +5 gold dragon scales. A wise player will stash a few scrolls of enchant weapon and scrolls of enchant armour to maximize his chance of manufacturing the required item.

If you don't have enough of a particular consumable item to open a treasure trove, you will eventually be able to find what you're missing by exploring the Abyss or Pandemonium for long enough. Whether or not doing so is worth the risk and tedium involved is up to you.

If you don't remember where you last saw a particular item, don't forget that pressing Ctrl+F will let you search for specific items you've already come across. This can save you a tremendous amount of time backtracking.


  • In 0.25, scrolls of fog and fear were added as trove fees.
  • Prior to 0.24, troves could ask for 12+3d4 scrolls of identify.
  • Troves that take all your piety were added in 0.16. Also, troves asking for the horn of Geryon didn't take it away from the player previously.
  • Prior to 0.8, troves worked differently: instead of always asking for an item and being untimed, they began with a very long timer (around 10000 turns). When attempting to enter, the player would be prompted to pay one of two amounts of gold: a large amount (usually around 2000-4000 gold) to enter the trove now, or a small amount (around 200 or so) to 'fix' the portal. The latter choice would make the trove untimed, but it would then require a specific item to enter, much as troves do now; the player would not know the item required until after they had chosen to fix the portal. The choice was removed because it was always optimal to pay to enter if you could - it is always possible to find more gold if you need it for something else, but there is no guarantee of being able to find the right item anywhere in the dungeon.
  • Troves were introduced in 0.6.
