Megiddo

Megiddo (神之怒) is Physics Magic used by Rimuru Tempest to gather ten thousand Souls for his Harvest Festival.

Effects
This magic uses Spirit Magic to create small water droplets shaped by Water Elementals to create lenses that focus light into laser beams that are deadly to even rank A humans like Folgen. Smaller water droplets are then used as mirrors to redirect the lasers toward the targets.

This process is very energy efficient as the attack that ends up striking the target itself uses no Magicules, Natural Energy, or Spiritrons, and any anti-magic barriers are entirely useless against the beams.

Weaknesses

 * It can only be used at daytime.
 * Scattering fine particles like dust or sand can impede or negate the attack.

Argos
Utilizing the same principle, Rimuru created the large scale surveillance system Argos.

Trivia

 * Rimuru gained the inspiration for this magic from Hinata's Disintegration Magic.
 * The name of the Magic, "Megiddo," is the Hebrew word for, as well as the name of a place in Israel called , which is the prophesized location of the final battle between good and evil.
 * The sunlight power density is about 1400W/m2. To reach the power of industrial metal laser cutter i.e. around 5000W, the main lenses focusing sunlight need to be at least 3.57m2 in surface area or 2.14m in diameter, assuming no energy were lost. Therefore, the rendition in anime is somewhat accurate.
