Cover art has a weird hand for the monkey, and I don't think there will be that much action in a monster fight, he just uses change... the most action I've seen in this manga so far was he running after and biting a slime. This is not a complaint though, I'm enjoying this pace.
As if he wasn't too OP before he started investing his points in stuff other than search and inventory...
I see now, he just got bored and wanted to have some fun.
Isn't he killing slimes every day? Doesn't he consider them monsters anymore or is he just doing it so mechanicaly now that he even forgets he's doing it?
