Rimuru Tempest has never really been one for battle. He’ll fight to defend his friends, but that’s about it.When Shion is found dead, all bets are off.Rimuru finds the invading Falmuth warriors and casts one of the most one-sided spells in anime. Rimuru flies into the air high above the soldiers and casts Megiddo. The magic works by creating small water droplets in the air that then reflect beams of light. Those beams of light are then focused into laser beams and sent through the heads of Rimuru’s enemies.
The attack is incredibly effective as the attack itself doesn’t use magicules, natural energy, or anything other than sunlight itself to kill its opponents. Megiddo wiped Falmuth off the map before they could ride into battle. Rimuru then used the souls of the people he had just killed to transform into a Demon Lord, gaining even more power for his enemies to fear.

3Shadow vs. Beatrix and Iris - The Eminence in Shadow
Even Two-On-One, Shadow Didn’t Break a Sweat
