The first thing Ackster did after clearing a path for him, Mio, and the bird was to sit down and breathe to restore his condition. He had exhausted himself, his sources, and his skills. Even if he could just ignore his injuries and fatigue since he would recover even when walking or advancing through the Alchemaze, the golem was proof he was fighting opponents stronger than anything he had ever fought.
He had almost died just now. In fact, it wouldn't have been weird if he had died. And that was the first being he encountered after entering the Alchemaze's depths. Ackster couldn't even begin to fathom what else he would encounter. But whatever it might be, it would certainly be stronger or harder to kill than the golem.
"Here. Eat up."
