Ring of aggravate monster
A ring of aggravate monster is a type of ring that appears in NetHack.
Contents
Generation
Wizards will never receive a ring of aggravate monster as either of the two random rings in their starting inventory.[1][2]
9⁄10 of rings of aggravate monster are generated cursed, and the rest are uncursed or blessed with equal probability. General stores and jewelers shops can sell rings of aggravate monster.
Description
A hero putting on the ring gains the aggravate monster extrinsic property. Wearing the ring doubles the effective level difficulty used to generate monsters[3]; the difficulty is capped at 50 after being doubled. Monsters will not wear this ring.
A hero eating the ring has a 1⁄3 chance of successfully absorbing its magic and granting the property as an intrinsic. This does not grant the doubled level difficulty, which is only a property of extrinsic aggravate monster.
Strategy
The ring of aggravate monster is undesirable in the great majority of circumstances, and typically relegated to polypile fodder. However, there are a few niche cases where generating more dangerous monsters is actually useful:
- For players attempting to generate a ki-rin or Archon to tame, one obstacle is the fact that these monsters do not generate in Gehennom, but are often too difficult for the Dungeons of Doom: wearing the ring solves this problem by not only making them more eligible, but much more likely to generate.
- Similarly, the higher difficulty monster generation also affects what is produced by the spell of create familiar.
- More difficult monster sacrifices are needed to receive the higher-tier sacrifice gifts, and can also raise luck higher than weaker monsters.
- For characters trying to reach experience level 14 to begin the Quest, more difficult monsters grant more experience points.
- Because level difficulty is capped at 50 after doubling, the ring can actually decrease level difficulty in very deep dungeon levels; Moloch's Sanctum, for example, can generate as deep as level 53. Similarly, in the End Game, the natural level difficulty is generally higher than 50 due to your experience level being a factor. The practical effect is fairly minor, however.
History
The ring of aggravate monster first appears in Hack 1.21 and Hack for PDP-11, which are based on Jay Fenlason's Hack, and is included in the initial item list for Hack 1.0. The ring also appears previously in Rogue, where it makes up 1⁄10 of random rings and causes monsters to attack more aggressively.
The modifier to level difficulty was added in NetHack 5.0.0. For a brief time in development, the ring augmented difficulty by a fixed 15 levels.

The Imperial Token is an artifact ring of aggravate monster that acts as the Gladiator quest artifact. It grants drain resistance while carried, grants regeneration and fire resistance while worn, and can be invoked for the leadership effect, which detects all pets on the level and increases the tameness of those within line of sight.
