Day twenty-six started with Eren staring at his own hand and trying to make it disappear.
At least he was trying to make a part of his body invisible and if it was possible at all.
The answer was, no. Partial invisibility was impossible which wasn't the end of the world for him. Eren just tried to test the limits of the op skill.
He'd been sitting on his platform since before dawn, eating the last of the wet cardboard mushrooms while mentally poking and playing with the Invisibility skill.
His mana pool was 50. The skill cost 10 mana per second. Simple math that even his failure math student days version could handle.
I get five seconds of invisibility before I'm completely drained and visible again.
Five seconds was nothing. He timed it against his own breathing. Inhale, exhale, inhale, exhale, inhale. Done. That was five seconds.
Eren did that too many times till yesterday and could time it almost perfectly now.
