Alongside the main story, players can also choose to take on the Arcane Realm, a separate area in which they may grind for experience, craft weapons and armor, and battle some mini-bosses. As a means to help the player progress, these bosses are sure to give players a run for their money during their playthrough of the Arcane Realm.
7King Slime (Forest Arcane Realm)
After fighting it in the Tower of Eternity, King Slime reappears in the Forest Arcane Realm as a mini-boss. Like with all Arcane monsters, defeating the King Slide will yield passage to the next part of the Arcane Realm.
King Slime’s attack pattern is identical to that ofits counterpart from the Tower of Eternity. However, one noticeable difference that should not be ignored is that the King Slime in the Forest Arcane Realm is much faster than the one in the Tower of Eternity. Additionally, the first boss track is absent during this fight.

6Abyss Evil God (Force Realm)
Like King Slime, the Abyss Evil God is the Arcane version of the Evil God fought in the Corridor of Wisdom. It is fought while the player is progressing through the area, though its exact location will change each time the player completes the Force Realm.

The Abyss Evil God utilizes a lightning-based attack as its only means of offense. While this strategy may seem lackluster compared to other bosses in the Arcane Realms, this attack may do great damage if the player is not paying attention to what they are doing.
5Death (Passage of Bravery)
Aftercutting down numerous enemiesthroughout the Passage of Bravery, the player is pitted into a one-on-one showdown with none other than Death itself. Much like King Slime and the Abyss Evil God, Death only has one attack at its disposal: it transforms into a ball of dark energy before smiting the player. This attack is not only capable of dealing massive damage, but it also takes up the majority of the area.
As a precaution, it is highly advised for players to pay attention in order to avoid taking heavy damage. Otherwise, the only other means Death has of harming the player is to summon ghosts for the player to deal with. After defeating it, it is later revealed that Death is one of three bosses that are subservient to the Demon Lord, who rules the entirety of the Demon Frontier.

4Warlock (Force Realm)
As one of the Demon Lord’s three subordinates, the Warlock proves to be a far greater foe than the Abyss Evil God. Faced at the end of the Force Realm, defeating the Warlock yields an Elite Demon Stone, which the player can useto craft stronger weapons and armor.
The Warlock uses multiple lightning spells to throw off the player and keep them from hitting him in battle. At the same time, he also summons rows of fire to surprise the player. These attacks make the Warlock overwhelming at times, but the pattern of his attacks makes him very predictable.

3Medusa (Forest Arcane Realm)
Medusa resides at the end of the Forest Arcane Realm. Similar to the Warlock, Medusa can be very overwhelming at times due to the frequency of her attacks. True to her namesake, she has the ability to briefly turn the player to stone if her opponent is rash in attacking her.

Medusa is also able to summon at least two Snake Wizards to draw the player away from her. She can also summon rows of water at random locations to surprise the player. Less predictable than the Warlock, Medusa proves to bea true force to be reckoned with.
2Succubus Celith (Corridor of Wisdom)
After completing the trials of the Corridor of Wisdom, the person who waits at the end appears to be Magaleta, Senia’s sisterwho ventured into the Tower of Eternity. However, this quickly turns out to be a ruse by one of the Demon Lord’s subordinates: Succubus Celith.

Like with most Arcane bosses, Succubus Celith can summon enemies to help her out in battle, though she will disappear in the process, forcing the player to do away with the monsters she has spawned. In addition, Succubus Celith will also fire a wide beam of light, though this can easily be avoided. The battle against Succubus Celith can be tricky, but her significance to the story cannot be understated.
1Michael (Sanctum Arcane Realm)
Faced at the end of the Sanctum Arcane Realm, Michael, aptly named after the archangel in Christianity, is the last Arcane Realm boss the player may face. Like with most Arcane Realm bosses, defeating Michael yields an Elite Sanctum Stone, the last kind of Elite Stone the player is able to receive.
In battle, Michael boasts an attack pattern similar to that of Medusa from the Forest Arcane Realm. He will often summon a pair of Cherubs or Ange, interns to help him out, as well as summon lightning bolts to strike the player. But in addition, Michael also has a laser attack that will fire at the player exactly five times. Combine these abilities with his immense speed, and Michael serves as a fitting boss for the game’s last Arcane Realm.
