Ose

Ose, Dreamer in a Drowned City is a spirit that appears in dNetHack, notdNetHack and notnotdNetHack.

Ritual, seal and taboo

Ose's seal must either be drawn underwater, with the hero chatting to it while they are also submerged, or drawn on dry land in the Lost Cities. If the seal is drawn underwater, that water will be drained away as part of the ritual.

A hero bound to Ose must not fall into water.

Mark

A hero with Ose bound has a gaze that carries tangible weight, and its force can be felt from a distance. The hero can hide this effect by blinding themselves or wearing a metallic helm that is not a helm of telepathy. For all heroes that are not Wizards or incantifiers, a cornuthaum will work as well.

Benefits

While bound, Ose grants the hero immunity to death effects and skill in tridents.

Ose's active powers are as follows:

• Querient Thoughts: The hero can release a blast of psychic static that damages all telepathic monsters on the level, and can also damage non-telepathic monsters with a ¹⁄₅ chance of occurring for each monster.
• Great Leap: The hero can level teleport at the cost of 625 nutrition.

Ose's passive powers are as follows:

• Plain Leap: The hero is capable of jumping.
• Maddening Thoughts: The hero gain a bonus to certain weapons based on their insight, as if they were a Madperson.
• Opened Mind: The hero casts spells using their charisma score.

In notdNetHack and notnotdNetHack, Ose, @, also appears as a monster that can be summoned by an Illithanachronounbinder. Ose is referred to by "she", though her spirit form may use either "he" or "she". As a monster, Ose is a neutral human that is amphibious, unbreathing, strong, and is an overlord to her kind: she can see invisible, is capable of flight, will pick up and collect items, and can follow the hero to other levels if she is adjacent. Like many spirits, she cannot be tamed.

Ose has a weapon attack, a sleep-inducing breath weapon and a claw attack that can splash targets with Lethe water. She possesses fire resistance, poison resistance and stoning resistance.

Generation

Ose is first generated when summoned from her seal by an Illithanachronounbinder. She is always created hostile, and is not a valid polymorph form or genocide target.

Ose is always generated with a +9 misty mithril trident, high-elven gauntlets, high-elven plate, a high-elven helm, and a shield of reflection.

Ose does not leave a corpse upon death.

Ose's natural 14 points of AC (or -4) is further bolstered by the high-elven armor she wears, and the reflection from her shield makes several types of ray attacks ineffective. She can also move at 15 speed and has the maximum MR score of 100.

If Ose is killed after being summoned, she can be encountered again in the Void, a branch accessed by opening the high altar of Ilsensine the Fallen as an Illithanachronounbinder using the invoke effect of The Elder Cerebral Fluid. Ose is placed randomly along with many other spirits of the near void on the second floor of the branch, and is generated with the "whispers" template, which makes her nonliving.

Messages

The sea-bottom within the seal fades, as if it were silt settling out of muddy water.

You initiated the ritual with Ose's seal underwater.

There is a sleeping <race> in the center of the seal.

You initiated the ritual with Ose's seal in the Lost Cities.

You suppose <he/she> could be called comely,

though to be honest <he/she> is about average among <the race> you have known.

The <random race>'s eyes open, and you have a long negotiation before achieving a good pact.

You successfully bound Ose to yourself. This last message has a ¹⁄₂₀ chance (5%) of being printed.

You know that this is Ose, despite never having met.

As above, with the other 95% chance.

The seabed rises.

You bound Ose successfully by performing the ritual underwater, and the squares containing you and the seal are replaced by normal floor squares.

The <sea bottom/dust> swirls below your weapon, forming into thousands of reaching arms.

You successfully bound Ose to The Pen of the Void, with "sea bottom" or "dust" used depending on where the seal was engraved.

The <silt/dust> in the seal swirls a bit. Otherwise, nothing happens.

You feel wet....

You performed the binding ritual incorrectly.

Encyclopedia entry

Long, long ago, before your ancestors had discovered flint or fire or songs, my people were already climbing the great heights of civilization. Settling on an island in the midst of the lonely seas, we raised a great city to the stars.

...But Time sweeps away all things, and that shining city has long since drowned beneath the uncaring ocean.
