It started quite "meh". Not like it became "peak" by the end of the episode, but... The magic can become interesting here. It's not breaking the existing rules (the way they were presented), but rather expands them, and acquisition of the power was simple, but it made sense and was effective (obviously). I already can tell, that the guy will eat the godstone next episode and probably get further boost, which may worsen the story-telling, but we'll see.
I am not sure about the isekai aspects here. I do not think they add much. They have already shown some "divine seals", and their "divinity" probably could have explained the "unexplained knowledge" within the rules of this world without the potential reincarnation. It may still turn out to be the case here, but it will most likely be a reincarnation and memory slowly getting back to the guy. I am giving it a chance for now, though.
