Aggravate monster

The aggravate monster intrinsic greatly amplifies the chance that nearby sleeping monsters will be awakened if you move near them. It is gained by the ring of aggravate monster, by eating a cat or dog corpse (or their less or more grown up forms), or by attempting to sacrifice a former pet ("So this is how you repay loyalty?").

The aggravate monster monster spell wakes up all monsters on the level and has a one-fifth chance of unparalyzing paralyzed monsters on the level. Some other effects have the same result, such as a shrieker's shriek, quaffing a cursed potion of invisibility, attempting to turn undead with your god extremely angry at you (or as an undead while lawful or neutral) or in Gehennom, and occasionally sitting on a throne or failing to read a spellbook ("You feel threatened."),
