 [Lionheart Skill Introduction]

Image	Skill Name	Skill Description
	Gale Kick	The form of swiftly approaching and overpowering enemies like a gale to confuse them, making them unable to react.
	Tiger Fist	The martial art of instantly overwhelming enemies with incredible power like a fearless tiger roaring.
	Assault Strike	This technique vibrates the space itself to unleash explosive Inner Force like raging thunder and sandstorm, violently shaking the surroundings and stunning enemies.
	Terrorizing Crash	Compressing one's Inner Force to the extreme, this destructive technique instills extreme fear in surrounding enemies with unbearable killing intent and nullifies their energy.
	Powerful Quake	By imbuing the ground with mighty Inner Force, a Lionheart can generate a deep shaking underground and explode multiple shockwaves to trip nearby enemies.
	Neutralizing Strike	This advanced oppression technique precisely injects Lionheart's inner energy into the enemy's energy path, inflicting critical damage and neutralizing the target.
	Hardened Bulwark	Using the power of the depth of one's body to emit Inner Force, this secret defensive technique of Lionheart envelops the entire body with a barrier of Inner Force, reflecting enemy attacks and minimizing impact.
	Encircling Capture	Energy emitted from the fingertips forms a barrier in front, and the enemies that are sucked in are bound by chains of energy woven with fighting spirit, instantly pulled to the center.
	Flurry of Strikes	Raising the body's power to its extreme and spinning the entire body like a whirlwind, this technique fiercely drives one forward as if imbued with the energy of a ferocious tiger.
	Healing Technique	This skill restores one's Inner Force by utilizing Lionheart's powerful ability to control energy flow, allowing wounds to quickly heal and continue fighting.
	Flash Assault	Lionheart's well-known charging form, rushing to enemies in a flash and striking them from behind to knock them with mighty force.
	Meteor Smash	The deadly attack technique of harnessing the energy of heaven and earth to annihilate the surroundings with intense shockwaves, like a meteor falling from the sky.
	Rampaging Lightning (Ultimate)	The ultimate form of surrounding the enemies with lightning-like electric chains emitted from one's hands, continuously bombarding them to disrupt their formation and shatter morale.
