Hel's Playground

**Hel's Playground** (閻魔の闘技場) was previously a Hell-type event that ran from 28/01/2020 to 12/02/2020.

It was made permanent, together with **Enma's Arena** and **Osiris' Realm of Judgment**, on January 31, 2023.

## Overview

* **Unlocked upon clearing The One-Eyed Dragon ~Mutsu (Rikuzen)~ (Story Ch. 30).**
* Hel's Playground is **high-difficulty content** divided into three main difficulties:
Normal (普通), Hard (難しい) and Ultra (超難).
	+ Each difficulty features its own set of stages, referred to as **Floors** (層).
	+ Each Floor features customisable conditions, referred to as **Trials** (審議), which are similar to **Risks** in Arknights' Contigency Contract-type events.
* Upon completion of a Floor, a fixed number of **Hell Tegata** (地獄手形) will be deducted from your current total (1/2/3 for N/H/U difficulties respectively).
	+ Note that Tegata are not consumed even if you fail or withdraw while challenging a Floor.
	+ Tegata restore at a rate of +3 daily (at 4AM JST, or UTC+9 timezone).
	+ You will not be able to attempt a Floor if you have insufficient Tegata.
* Complete Floors and missions in order to obtain **Blue Souls (青の霊魂)**, and trade them in for various rewards in the **Trading Post** (交換所).

### About Trials

* **Trials** (審) are "bonus points" awarded by selecting various enemy-buffing conditions in each Floor.
* In order to obtain the full amount of points, you need to complete the Floor while **keeping all Warehouses intact** while the selected conditions are active.
	+ If **any** Warehouse is lost, you will not gain any points at the end of the Floor.
* Trials are cumulative and will be added to a **total** visible from the Floor selection screen.
* Every day (at 4AM JST), you will be awarded your current Trials total + 10 additional Blue Souls as your "daily income" for Hel's Playground.
	+ Any income not claimed before the next daily reset will be forfeited.

### Miscellaneous

* If you are having difficulty clearing a Floor and do not care about fulfilling any Trials, you can opt to activate the **Blessings** (加護) option located to the top-left of the 3x3 conditions grid, which will **double your units' stats** for the duration of the Floor.
	+ Note that you will not be able to attempt any Trials (0 bonus points) if Blessings are activated.
* Similar to general stages, you will be given the option to **autocomplete** Hell stages if you successfully clear it without having any of your units incapacitated in-battle (*taiha*), and keeping all Warehouses intact.
	+ Note that autocompleting any Floor still costs 1 Autocomplete Ticket, and you will not earn any Trials (0 points) by autocompleting it.
* On certain days, some Floors may have a red **ボーナス** (bonus) text at the top-right. Clearing these Floors will net you 1.2x more Red Souls than usual.

## Trivia

**Hel**, in Norse mythology, originally the name of the world of the dead; it later came to mean the goddess of death. Hel was one of the children of the trickster god Loki, and her kingdom was said to lie downward and northward. It was called Niflheim, or the World of Darkness, and appears to have been divided into several sections, one of which was Náströnd, the shore of corpses. There stood a castle facing north; it was filled with the venom of serpents, in which murderers, adulterers, and perjurers suffered torment, while the dragon Nidhogg sucked the blood from their bodies. Mention is made in an early poem of the nine worlds of Niflheim. It was said that those who fell in battle did not go to Hel but to the god Odin, in Valhalla, the hall of the slain.

**There are nine realms in Norse Mythology**, they are called **Niflheim, Muspelheim, Asgard, Midgard, Jotunheim, Vanaheim, Alfheim, Svartalfheim, Helheim**. The nine worlds in Norse mythology are held in the branches and roots of the world tree Yggdrasil. These realms are the home of different kinds of beings, such as Asgard the home of the Gods and Goddesses, or Jotumheim the home of the giants.

The first two realms, Niflheim and Muspelheim were created out of Ginnungagap. The rest of the realms were created out of Ymir’s body by Odin and his two brothers during the creation of the world.

It is not a coincidence that there are nine realms, the number nine is an important number in Norse mythology, and its significance can be found in other poems in the Edda’s by Snorri Sturluson. To mention a few, Odin hung on Yggdrasil for nine days and nights, Heimdall has nine daughters, Njord had to wait nine days for Skadi.
