Kapitel 551: An Up-Hill Battle

After finishing the slaughter of the 11th wave, Leo reappeared, glancing at his Mana and Stamina bars with a faint click of his tongue.

His Mana bar had dropped to a mere 30%, and although it was rapidly refilling thanks to his newfound abilities as a master, he did not expect his mana bar to fall too steeply so fast.

[Vanish] was like a leech on mana, and although the version of the skill where he blended with the shadows did not consume as much mana, the one where he outright disappeared in light, consumed a lot.

However, while his mana was lower than he expected the real issue he was facing was his stamina.

While invisible, Leo's Stamina had plummeted from 60% to 35%, as despite being unseen by the opponent, the effort required for him to move swiftly and strike from random angles without detection had taken a toll on him.

The strain of constantly relocating for surprise attacks was far from negligible and left Leo in a vulnerable position.
