Sustain ability
Sustain ability is a property that occurs in NetHack and prevents most changes to a character's attributes.
The only source of the property is wearing a ring of sustain ability.

Description
Sustain ability prevents attribute changes from exercise or abuse, as well as blocking the parts of item effects that change attributes:
- Applying a cursed unicorn horn
- Eating the corpse or tin of a giant
- Eating a tin of spinach
- Quaffing a non-cursed potion of gain ability
- Sitting on a coaligned altar
- Intelligence loss due to Mind flayer's brain eating attack
Sustain ability does not prevent changes to attributes from polymorph, including the shuffling that occurs when polymorphing into your own race.
