Water Blade

Water Blade is a Common Skill used by Rimuru Tempest. It can shoot out a thin water blade with tremendous cutting power.

Description
Following the principles behind Hydraulic Propulsion and Water Current Control, Rimuru (unnamed at the time) trained with the idea of "cutting water." After a week of practice, he had increased the pressure of his Hydraulic Propulsion's water gun enough to cut through a boulder, acquiring the skill. Water Blade, Water Current Control, and Hydraulic Propulsion then evolved into the Extra Skill Water Manipulation.

Trivia
