The official english captions for this sentence gives:
もう戦う気力も尽きかけている。= My powers grow with each battle.
but google translate gives
I'm running out of energy to fight.
Or maybe the translator who wrote the official english captions thought it was:
もう戦う気力も付きかけている
I realize that there was another post that is similar to my own, but that question seems to not have been answered: 気力がつきかけていた: What meaning does かける have here? And which つき is this?
