Soul

**Souls** (魂) are powerful equippable items that provide a massive damage boost against enemies that match the soul's type.

## Prerequisites

Souls can only be equipped on SSR Weapons that have been **Tempered** (聖錬) at least **once**.

Thereafter, players can select any of the bottom three slots to equip a Soul in, and the bonus damage multipliers will be applied to the character in question accordingly.

## Obtaining

Souls can currently be obtained in two ways:

* As an **extremely rare** drop from Expeditions.
	+ You can obtain multiple copies of the same Soul type this way, but whether or not they stack is unknown.
* Clearing **Lv100 Abyss Bosses** in the Sealed Den of the Abyss (深淵の封穴).

## Soul Effects

* There are currently **14** types of souls, 9 can be obtained from Abyss Bosses, while the other 5 are obtained from Expeditions.
* Souls give a **x1.50** damage boost at **Lv1**, and give a **x4.40** damage boost at **Lv10**.

### Soul Strengthening

Souls have **ten levels** and can be upgraded using **SSR Shiraz Flowers**, with the success rate getting lower and flowers cost per level getting higher with every successive upgrade.

Purchasing the **Daily Flarelight Set** adds +3% to the success rate.

You can use **Azure Dust** to increase the success rate (+5% / 20 Dust, up to 100%).

## Applications

Since Souls are limited to a specific enemy type, their effectiveness largely depends on what Souls you already have (or are planning to get), and the variety of enemy types you encounter across different stages.

In general, you should equip Souls on characters with **multi-hit Abilities** such as Lydia and Naja, since their pre-emptive multi-hit attacks can quickly decimate enemies specific to the Soul type(s) you have equipped on them before their turn(s) even begin.

You can also equip Souls on characters with **multi-hit Sprout Arts** such as Ladis, Beatrice, Koto and Sharon in order to achieve a similar effect.

### Trials

Souls are especially useful for manually clearing the **100 waves segment** of each Trial. The following table lists some effective Souls to have equipped on your characters for each trial.

 Enduracia's Despair

### Sealed Den of the Abyss

* The **Demon Beast Soul** (魔獣の魂) is effective against **Ruinous Beast** (望滅の凶獣) and **Pentagoa Shisshi** (ペンタゴア・シッシ).
	+ However, obtaining said soul requires clearing Lv100 of **Alluring Kotatsu Slime** (魅惑のコタツスライム), which is **more difficult** than perfecting Ruinous Beast, but **less difficult** than perfecting Pentagoa Shisshi.
	+ If you attempt the Abyss Bosses from bottom-to-top (easiest to hardest), you will be able to use it for Pentagoa Shisshi, and then use it for Ruinous Beast later if you decide to grind previous bosses for **Magic Cards** (魔札) in the future.
* The **Slime Soul** (スライムの魂) is effective against every Slime Abyss Boss, however, obtaining it requires clearing Lv100 of **Al Marid** (アル・マーリド), who is the second hardest Abyss Boss at the current time of implementation (March 16, 2021). Its use is pretty much limited to grinding Magic Cards for previous Slime bosses.

### EX Hard Story Missions, Event Stages and Collection Quests

* The **Angel and Golem Souls** are very useful for the EX Hard difficulties of later Main Story chapters.
* Every event features different enemies, and you can view the enemy types of each stage before attempting them, so organize your team and souls accordingly!
* For players grinding **Shiraz Flowers** with Laura, the **Opal and Devil Souls** are useful for letting her one-shot enemies in order to maximize stealing efficiency given the limited number of skills she has.
