A loadstone is an undesirable gem to have on your person. It is extremely heavy and almost always generated cursed. Unlike most items, you cannot drop it or place it into a container while it is cursed. You can get rid of it if you lift its curse somehow, e.g. by scroll, spell, holy water, or dipping it into a fountain.
You can wield a loadstone, but you cannot uncurse it with a scroll of enchant weapon. For all its weight, a loadstone does not do any more damage than flint when thrown.
Loadstones autocurse when they are dropped or leave your main inventory in any other way. Most loadstones encountered in the dungeon are cursed; the only exceptions are 1/11 of those generated inside containers (the other 10/11 are generated cursed).
Loadstones are also one of the most easily picked-up items in NetHack. Any setting of the pickup_burden variable will be ignored if the character attempts to pick up a loadstone, and other inventory restrictions may be ignored as well -- if a character's knapsack has already reached the 52-item limit, the loadstone's inventory letter will be a pound sign (#)!
The easiest way to test if a gray stone is a loadstone is to kick it before you pick it up. Take off any items that add to your strength or kicking capabilities: remove gauntlets of power and kicking boots first, and make sure you are not a class that uses martial arts (samurai or monk) or polymorphed into a creature that has a bonus to kicking, such as a sasquatch. Loadstones are heavy enough that they cannot be kicked under normal circumstances (unenhanced strength, not on ice, no kicking bonus from class/equipment/polyself).
If for any reason you cannot (or do not want to) prevent yourself from having kicking bonuses, you can compare kicking ranges. A loadstone should travel much less far than a harmless gray stone or any object of similar weight, like a rock. Be careful though; some bonuses add a small random amount to the distance. Do not kick fragile objects.
Loadstones autocurse when they are dropped (or put in containers), not when they are picked up. Cancelling a suspicious gray stone will permit you to safely pick it up and drop it afterward.
Loadstones are normally generated cursed, so an unknown gray stone on the floor is likely a loadstone if a pet will only "reluctantly" move over it. This method still works on stones stuck next to undiggable walls, but beware of traps.
A loadstone generated inside a container will have a significant weight, and you usually get a pickup_burden warning when indirectly lifting a loadstone.
You can #name or formally identify a loadstone. This way you will then recognize any future ones.
If you need to read a noncursed scroll of remove curse for other reasons anyway, you might want to deliberately pick up a known loadstone. You can also cancel a known loadstone in advance, so that you can drop it easily.
In order to get rid of a cursed loadstone, you can try the following strategies:
- Pray; having a cursed loadstone counts as a minor trouble
- Read a noncursed scroll of remove curse and drop the stone
- Dip the stone in holy water and drop it
- Dip the stone in a potion of polymorph for a chance of transforming the stone into a valuable gem (or, failing that, something that can be dropped)
- Allow a nymph or other item-stealing monster to take it
- Cast stone to flesh on yourself (drop everything lithic that you don't want to transform into meat first)
The name loadstone is a pun on the word lodestone, a naturally magnetic mineral.
In slash'em, healthstones are also always generated cursed. So pet testing will not be enough to recognize a loadstone in a undiggable corner.
Be careful not to throw a loadstone. If you have autopickup on, you automatically pick up any items you have thrown.
As you can see the weight of items, it is much easier to avoid picking up a loadstone. Drop a junk item on any suspect gray stone: this forces the pickup menu to appear since there are now several items. Gray stones weighing only 10 are harmless to pick up.
In Slash'EM Extended, a loadstone fired with a sling does a whopping d40 damage if it hits. Autopickup is smart enough to avoid picking up known cursed items, so if you were diligent enough to try to drop the loadstone while it was still cursed (which makes the BUC status known), this will not cause you to pick it back up when you walk over its location.
Additional ways to get rid of a loadstone:
- Polymorph into a lithivore and eat the loadstone.
- Wield the loadstone and read a noncursed scroll of enchant weapon to remove the curse. Beware that here, cursed loadstones will weld themselves to your hand.
- Because gems can be enchanted in Slash'EM Extended, if you read enough cursed scrolls of enchant weapon, a wielded loadstone will blow up (this is a huge waste of resources though).
- Trigger an item teleporter or be attacked by a monster with the item teleportation attack. Certain items can also teleport the player's items out of the inventory.
