A ring of sustain ability can be identified by dropping it down a [[sink]] (with a 95% chance of losing the ring in the process), or by wearing it and doing something which ought to change your attributes like eating a poisonous corpse without [[poison resistance]], eating a tin of [[spinach]], quaffing a non-cursed [[potion of gain ability]], #sitting on a coaligned altar, or applying a cursed [[unicorn horn]]. Alternatively, zap a [[wand of enlightenment]] and look for the line "You have fixed abilities".

The ring of sustain ability is a ring found in Nethack that gives you the sustain ability property, which means that your base attributes cannot go up or down, except by polymorphing into your own race.

Strategy

Simply wearing the ring constantly will prevent your attributes from being increased through exercise, but can also be used to prevent stat loss from constant abuse, e.g. by being satiated for long periods of time to save food. It is also beneficial in short-term scenarios: for instance, if you lack poison resistance but have identified the ring early, it is useful to wear while eating poisonous corpses - this avoids the usual strength loss, and the ring can safely be removed after you have the resistance.

The ring can also be used to prevent the intelligence drain from a mind flayer's attack, but it does not directly protect against death by brainlessness; if your intelligence is already 3 when you put the ring on, then one successful brain-eating attack will still put an end to your game. The ring also does not stop the attack's amnesia effects.

Identification

In addition to identifying it via sink, you can use a wand of enlightenment while wearing a suspected ring of sustain ability; this will display the line "You have fixed abilities" among your attributes. A player can also identify a suspected ring by wearing it and doing something that would alter their attributes, e.g. eating a tin of spinach, quaffing a non-cursed potion of gain ability, #sitting on a coaligned altar, applying a cursed unicorn horn).

History

Prior to NetHack 3.6.1, a bug allowed you to use a ring of sustain ability to increase strength: When wearing the ring, if your nutrition status changes to Weak, your strength wouldn't go down as it usually does. However, if you then removed the ring and then raised your nutrition status to Hungry, your strength would increase as usual.

This could be farmed or abused to raise your strength to its racial maximum, provided that you have a large number of low-nutrition comestibles (such as meatballs). You first get your nutrition status to Hungry, and then:

  1. Put on the ring of sustain ability;
  2. Wait until your hunger status changes to Weak;
  3. Remove the ring of sustain ability;
  4. Eat a meatball (or enough meatballs to go from Weak to Hungry); 5) Repeat steps 1 through 4 until your strength reaches its racial maximum.

A ring of hunger, conflict or regeneration will speed up this process. Beware of possible negative effects, especially if the ring is cursed.

This would be especially productive for characters who start with low strength and the stone to flesh spell, such as Healers.
