Kraken's Whirlpool

Narrowing his eyes, Alex stopped holding back.

Opening his skill tree, Alex learned a new skill without hesitation.

[Energy Slash]

[B-rank]

[Effect: Gather mana into your weapon and slash it at your enemy to deal damage that is equivalent to the amount of mana that you use multiplied by 3.]

[Cooldown: Null]

This skill doesn't have any cooldown probably because the damage it can cause is dependent on the mana that the user outputs.

That means, if Alex used 10 mana to activate [Energy Slash] he can cause 30 damage to the enemy.

By the way, this skill cost Alex 20 skill points even though it's just a B-rank skill.

This just shows how powerful this skill is even if it's just a B-rank skill.

Looking at his new skill, Alex sighed.

'I should've done this from the beginning, I just wasted my time,' he thought.

Shaking his head, he turned his eyes back at the squids that were rushing towards him.
