Known as one of the most successful and beloved anime series within the Isekai genre, “That Time I Got Reincarnated as a Slime” has expanded across various media platforms such as light novels, manga, and now boasts three seasons of anime. The captivating world presented in “That Time I Got Reincarnated as a Slime” is filled with familiar fantasy elements that many fans recognize. The story revolves around Rimuru Tempest, a slime residing in the Central World, who embarks on an extraordinary journey to adapt to his new life as a reincarnate. As he confronts the challenge of creating a sanctuary for monsters, he is assisted by the Jura Tempest Federation, a group that aids him in this endeavor.

In this anime, various types, styles, and manifestations of magic drive both the fighting sequences and the overall plot progression. The effectiveness of these magical powers is influenced by the concepts behind them, adhering to the magical rules and principles within the show’s universe. This anime boasts some of the strongest magic portrayed in the realm of anime, with the strength of abilities largely depending on the caster, their magical energy input and output, mana levels, and other factors. Not all powerful spells are strong due to their raw power or destructive capabilities; rather, they can be considered potent because of the intricacies involved in casting them and the difficulty in executing them effectively.

7 Meggido

The Fury Of The Gods

  • Current User: Rimuru Tempest

Megiddo is an intricate incantation devised by Rimuru, serving to amass numerous spirits for the annual celebration. This novel form of sorcery, termed Physics Magic, possesses a purely physical energy discharge. Consequently, it neither interacts nor impacts magic-wielding entities, or magicules, making it impervious to magical blockades.

This magical ability molds big water droplets into convex lenses, focusing sunlight into intense, narrow beams of high heat. Smaller water droplets serve as mirrors, quickly redirecting these beams. However, this spell is only effective during daylight and can inflict severe damage, particularly when used against large groups of enemies.

6 Disintegration

In the world of “That Time I Got Reincarnated as a Slime,” this particular enchantment represents the most potent form of Holy magic for offensive purposes. Known as Disintegration, it’s an overwhelming force that initiates a rapid breakdown of matter for anything inside its casting area. This cataclysmic event swiftly dissolves the physical and spiritual components of any objects or beings within its reach.

The spell’s potent impact is significantly confined by its reach, making it suitable only for smaller creatures, as it doesn’t work on larger ones such as True Dragons and Charybdis due to their immense dimensions. However, certain versions of the spell, like Sanctuary or Trinity Disintegration, are exceptions to this rule.

5 Drago Nova

Dragon Star Explosion Supreme

  • Current User: Milim Nava

Milim Nava’s formidable star magic harnesses the strength of the Star King Dragon Veldanava. Unlike conventional magic spells, this one demands stardust instead of magicules for casting. The practitioner concentrates stardust in their hands and unleashes a staggering burst of energy that can obliterate any obstacle.

Without proper control, the force of this spell could wreak havoc and quickly level any landscape, potentially annihilating the Central Realm. Its power is so immense that it must be severely restricted to prevent widespread devastation. Other versions of the spell, such as Drago Buster, are less potent but still possess a substantial destructive capacity, capable of demolishing Charybdis.

4 Nuclear Flame

Flame Of Doom

  • Current User(s): Carrera, Rimuru Tempest, Ultima

This magical incantation possesses an incredibly powerful energy akin to nuclear force. Similar to other spells categorized as nuclear magic, its execution demands adequate preparation or casting time, which may vary depending on the caster’s abilities. When activated, this skill unleashes a thermonuclear blast capable of engulfing and obliterating a vast expanse with a fiery detonation.

Lacua used this ability against Rimuru during an attempted assassination but was ultimately countered. Had Rimuru not intervened and blocked this attack, the ability would have caused untold destruction.

3 Nihilistic Banish

Dark Magic Disintegration

  • Current Users: Gadra, Ultima

As a fervent enthusiast, I’d describe Nihilistic Banish as a formidable dark enchantment reminiscent of the divine Disintegration spell. Unlike its holy counterpart, this spell calls upon energy from the Daemon realm, obliterating a chosen target much like Disintegration does with its holy mark. However, it’s important to note that its area of influence is limited and it’s not recommended for use on massive targets.

In contrast to the standard Nihilistic Banish, the modified spell named Nihilistic Parade offers a significantly broader spectrum of impacts. Capable of influencing vast swathes of a battlefield or landscape, it’s an ability that stands out within That Time I Got Reincarnated as a Slime. This unique skill is known to be wielded by only two entities throughout the entire series.

2 Death Streak

Blessing Of Death

  • Current Users: Guy Crimson, Testarossa, Ultima

A potent nuclear enchantment, known as the Death Streak, alters and restructures genetic material using a form of dark light energy radiation. This radiation pierces through both physical and magical defenses, zeroing in on the fundamental data that defines an individual, ultimately leading to their demise. The casting of this spell triggers a swift breakdown and disintegration of the victim, effectively annihilating their soul.

As a fervent devotee, I’ve come to realize that this potent charm possesses a vulnerable side. By balancing it with an equivalent measure of radiant darkness, one can effectively neutralize it. However, take heed: this spell, when unleashed, is almost invariably fatal, save for those fortified by spiritual light forms.

1 Abyss Annihilation

Terminal Decay Annihilation

  • Current Users: Carrera, Rimuru

The most potent version of nuclear sorcery, Abyss Obliteration, harnesses dark magic from the Daemon dimension to unleash an apocalyptic blast that can shatter realities. This enchantment works by drawing negative energy from the daemon realm and applying a force akin to a black hole’s gravity collapse.

The immense power of this spell means it holds the potential for catastrophic destruction, capable of not only obliterating our world but potentially a celestial body like a star as well. It requires extreme caution in its use.
