Early on he should actually invest in all stats equally, because if 10 points is his baseline, each point is a significant increase, and just getting a stat to 20 means he's twice as good as before. So I'd say, put points equally in every stat, until he gets 30 everywhere, and then specialize in 1 or 2 stats according to a thought-out strategy. Agility can be good, because speed lets you both attack and evade better. Intellect can be interesting depending on what the actual effects are, and it can also let him go the magic route. The rest of the stats are not too important, as long as he doesn't neglect them too much.
"He's the type of person to never forget a lesson that has been taught" how unlucky it is that he seems to have never been taught a lesson then lol. This stupid mc, I hope he **actually** gets smarter when he increases his int some time, and the author doesnt just make its only effect to increase his mp while saying "oh, my thoughts are more clearer now!" while staying a moron because he can only think moronic thibgs faster lol
the mc is already 20+ yrs old...even he didn't go to school ..plss make him smarter at least not like 10 yrs old..publishing ur current condition when the association keeping an eye on you...when he said that they need wielder magic to damage monster but why is he concentrating strength?didn't he at least realized that when he has 10 years of experience in the dungeon...i think it is better to increase intelligence and start up a business to have a better life...my gosh..
