Ring of protection
A ring of protection improves your AC by its enchantment.
Identification
It self-identifies when worn for the first time, unless it is +0.
Effects
For example, a +1 ring of protection improves AC by 1. Conversely, it increases your AC by its enchantment if it's negative. The enchantment can be altered by charging.
A ring of protection also increases your magic cancellation by 1, to a maximum of 3. This does not depend on its enchantment, and it does not stack with a second ring of protection.
Eating a ring of protection with non-zero enchantment has a chance of conferring intrinsic protection.
History
The ring of protection started boosting magic cancellation in 3.6.0, as part of that version's many changes to magic cancellation.
