Oetaru

### Assess Text

Attracted by the chants amplified by the cave system, OETARU has awakened and is awaiting its sacrifice.

*The cursed chants amplified by the cave system make you dizzy. To your horror you noticed has awakened something else...*

**Oetaru** is the boss of the Horrible History of Household Hell mystery.

## Appearance

Oetaru, appropriately nicknamed "the Inner Coil", is the visage of the human inner ear turned into a colossal monster of the sea. A specific frequency of sound is the only way to summon it, and sound is also its only observed means of attack. Should victims endure the deafening tones that Oetaru emits for too long, their inner ears will explode as they die.

Oetaru rises from an impossible hole in the surface of the ocean where the water appears to be inexplicably displaced by some cylindrical object. Additionally, the sky and horizon distorts in its presence.

## Story

Oetaru resides in the ocean near the OOO manor, accepting human sacrifices upon being summoned by a specific auditory frequency.

Following the recent owner of the manor disappearing from the public and ending up as a sacrifice for Oetaru, the player will investigate the manor and eventually discovery the sacrifice altar in an underground chamber. In order to summon Oetaru, the player must possess a Flashlight, use the flashlight to find the hidden speakers, and correctly set the frequency on the speakers to the randomized value found in the Shiokawa Herald (A). If the player does not fulfill these requirements, Oetaru will not be summoned, and the mystery will promptly conclude in ambiguity (Ending C).

After the speakers set to the correct frequency, Oetaru will appear when the player returns to the sacrifice altar, and a combat encounter will begin.

Oetaru is a unique boss that is immune to standard attacks (kick, attack, & strong attack) and possesses incredibly high health. The player is not intended to defeat Oetaru through conventional means. Instead, two special paths are available to the player.

* The simplest resolution to the combat is to simply run. To this end, the Oetaru fight adds a unique run action with extra flavor text, but the standard run action works as well. Escaping the fight in this manner enrages Oetaru, causing it to briefly attempt to chase the player before ultimately turning its sights on the fishermen of Shiokawa. The mystery then concludes with Ending B.
* If the player possesses the Ritual Dagger and has at least one Ally in tow, a unique sacrifice action becomes available. Choosing it will kill the player's first ally, immediately ending the combat encounter. Oetaru retreats beneath the waves, satisfied with the sacrifice. The player then destroys the speakers used to summon it, and the mystery concludes with Ending A.

The player must quickly decide on a plan of action, since Oetaru will always slay the player after 3 rounds of combat. This unique death is *not* one of the mystery endings.

It is also possible, though difficult, to defeat Oetaru the conventional way, by reducing its monstrous amount of health to 0 through the limited options for attacking it. While the player's equipped weapon is largely useless, Oetaru can be damaged by bullets, thrown items, and spells. Defeating Oetaru in this way is considered the same as running from the fight, and the mystery will conclude with Ending B.

## Location

Located in the end of Horrible History of Household Hell.

## Trivia

* In previous versions of World of Horror, one possible method of conventionally defeating Oetaru involved the use of pre-nerfed Expel Evil. To do so, one must choose ***Ath-Yolazsth the Towering Eye*** as the summoned god to spend DOOM point instead of REA to cast spell, so that the player could alternate the spellcasting between Expel Evil, any healing spell and any offensive spell to whittling down Oetaru's HP without the player died of sanity loss, blood loss or doomed. (note that pre-nerfed Expel Evil is a multiple-use spell)
* Another way was to spending turn finding and throwing melee weapons at it until it dies, providing the player has a means to surviving its attack.
* Currently, the spell Grow Teeth allows you to attack Oetaru through the Bite command. Chewing (no pun intended) through Oetaru's considerable HP pool will take some time given the relatively low damage of the Bite command. Fame-endowed Mizuki with a large following, including a Ryoko or two, could manage while still have enough spare Doom to survive the rest of the game. Otherwise, the Doom level might be too high to progress for very long baring extreme amounts of luck.
* Oetaru might be the Invisible Watcher from an event with the same name due to the similar visual between Oetaru's 'hole portal' and the one in that event.
