Megiddo in That Time I Got Reincarnated as a Slime

7Meggido

The Fury Of The Gods

Meggido is a complex spell created by Rimuru to harvest numerous souls for the harvest festival. The spell is a new type of magic called Physics Magic that has a purely physical power output. This means that the magic doesn’t interact with or affect magicules, which in turn makes it unblockable by magical barriers.

The spell shapes large water droplets as convex lenses to concentrate sun rays into very thin, high-degree heat beams. Smaller water droplets are then used as reflective surfaces to bounce off these beams at high speed. The spell’s main weakness is that it can only be used when the sun is up, but it deals devastating damage, especially to hordes of enemies when used.

Disintegration in That Time I Got Reincarnated as a Slime

6Disintegration

Spirit Particle Decay

This spell is a type of Holy magic and is considered the strongest offensive Holy magic spell inThat Time I Got Reincarnated as a Slime. Disintegration is a powerful attack that causes spiriton decay to anything within the casting circle and instantly eliminates the particles and souls of anything within that range.

The spell’s powerful effect is severely restricted by its range of attack. This limits its application to smaller monsters, as it cannot be used onlarger monsters like True Dragonsor Charybdis due to their enormous size, but variations of the spell, like Sanctuary or Trinity Disintegration, are the exception.

5Drago Nova

Dragon Star Explosion Supreme

This potent spell, created by Milim Nava, is a type of star magic that utilizes the power of the Star King Dragon Veldanava. The spell requires a powerful substance called stardust to cast rather than the magicules required for most other magic spells. The caster channels stardust in their palms and releases an unfathomable beam of energy that iscapable of destroying any barrier.

If left unchecked, the spell’s raw destructive power will swiftly destroy any terrain and can obliterate the Central World. The spell’s power is so great that its output has to be heavily limited so as not to cause indiscriminate destruction on a large scale. Other variations of the spell, like Drago Buster, are of a smaller scale but still considerably powerful, capable of destroying Charybdis.
