My build would be : Vit>Int>Dex>Wis>rest of stats
To be able to survive damage, be able to cast awesome magic, run fast and not be an idiot like JeeHan. As for the skills, I would try to get every combat mastery there is to lv 5-10 at least, to be able to defend myself from bad guys(but still not abyssal level), master stealth as far as possible and master magic alongside it. Crafting would be usefull ( building high quality shelters quickly and making all kinds of stuff, possibly upgrading them)
Now as for magic:
1) I would try mana crafting weapons of all sorts : swords, daggers, axes, spears, lances, maces and so on. I would grind that magic until about 35lv.
2)I would try talking with animals, maybe I could get a skill to talk to with them like doctor Doolittle, then I could make them my pets and hopefully get them into party and rise their level( try imaginig level 50 wolf as a pet: big like a horse, much stronger, faster and harder to kill, and I could rode it ),
3) I would also try to get time/space magic and summoning magic, master them a bit( lv 25+) and try to mix them together to get an awesome AoE space/time distortion summon spell, that could summon all of my pets ( Imagine all kinds of different predator or dangerous species at levels 50+ appearing out of nowhere and attackin the enemy, e.g. wolves, tigers, lions, serpents, snakes and.... gigantic spiders and scorpios) - kinda wicked summoner/pettamer
4) Healing magic - for survival purposes
5) Try making some skill along archers "Unlimited Blade Works" lines or "Gate of Babilon" that Gilgamesh had, and grind it
6) Try getting elemental affinities mainly water, earth, life(light), darkness, and wind
7) get mind control skill for those whom speaking normally to seems not to affect
Now for physical skills
1) Learn chi control, manipulation and accumulation ( probably would get me a boost in mp/hp regen rate)
2) Injure myself in order to get physical endurance to a really high level, and maybe a passive regeneration boost skill
3) Get injured some more with other elements like fire, electricity, cold, acids and bases(chemical), poisons, venons, toxic substances to get resistances to them, and of course I would go to Chernobyl to get radiation resistance in the end ( I would end up being more of a survivalist than a cockroach teehee)
4) master a few simple techniques from different martial arts, far above the combat Masteries ( e.g. jabs, hooks, uppercuts, roundhouse kick, lowkick, sidekick, and some throws)
5) DEFINITELY master parcour
6) train jumping a lot -> get jump mastery skill, maybe get an acrobatics skill
7) try rope walking to get passive balance enhancement skill
8) go to a tennis court or sth and set the ball-tossing machine on max speed and then watch the balls fly by -> get passive kinetic vision enhancing skill
9) go to a swimming pool and try to get enhanced lung capacity skill by holding breath underwater
10) run everywhere -> maybe get Running Mastery, Marathon Stamina skills, or at least get dex & vit for runing
11) do ropejumping -> get Coordination passive skill
as for interpersonal skills:
1) Lying Mastery ( obvious how)
2) Fools Act (get drunk like hell and start clowning around)
3) Rethorics ( reading a lot of books aloud to train pronouncing the words and talk with people a lot, cpuld probably grind lying mastery alongside it)
4) Bargaining passive skill ( by trying to haggle in a grocery store or sth)
5) TEACHING -> could be useful to be able to teach someone magic -> start my own Hogwarts School of Witchcraft and Wizardry, with added martial arts and assasination classes lol
6) Leadership passive skill ( could come in handy, maybe the party members would get buffs for my leadership level)
7) Sweettalking ( to get whom I want to do what I want)
mind skills
1) Learn all languages ( or atl least Russian, Japanese, Arabic, Korean, Spanish, Italian, French and maybe celtic runes and hierglyphs and Hebrew)
2) Learn Physics, Bilogy, Chemistry, and probably all other science related fields of wisdom
3) It would be good to learn construction or sth like that( maybe construction falls under crafting category, if so than no need ) to be able to build, repair and customize ships, boats, cars motorcyckes and so on
OTHER:
ID create and escape for obvious reasons
And with that set of skills appropriately grinded up to 50+ in the end( after about 1 year it would probably be feasible) I would start rebuilding the world the way I would like it to look. First I would seize control of the undergroud( mafia, yakuza, triad and so on), then, I would go for companies, after owing all major companies ( and half of the minor) I would try siezing power in my home country, reform it ( get rid of useless bureaucracy, corruption and other problems like unemployment and homelessness) change it into a powerful nation of incredible wizards/warriors/teachers/scientists/traders ( thanks to teaching and leadership skills), make the environment friendly houses, roads and means of transport ( based on elemental magic - Giant trees for homes, waterlines for transport, big windmills for additional energy and so on). I would also make one giant magical barrier around my country so that no one can attack it and there would be border crossings controlling who goes inside and outside and the guards there would be handpicked by me as the best wisards/worriors/martialartists that would never be corrupted.
After 50 or so years ( I would still be grinding my skills and stats in my free time from managing the country) thanks to my governing it, my country would be the mightiest country in the world, as well as the most healthy and environment friendly one , with fresh air, clean waters, and creatures out of fairytales roaming freely, and my people would by far surpass any other nation , be it scientifically, phisycally or magically, but thanks to the magical shield around the borders it would not wage any wars, nor be afraid of anyone invading it, so gaia shouldn't be too pissed off with me, and since I would do good deeds ( changing the underworld people into good guys) and so I would start spreading the knowledge and devices my people have accumulated, at first only the harmless things like magical air filters, water filters and other eco products.
After another 2-5 years I would spread healing magic to the most peaceful nations with the least crime rate and would share some medical achievements with them.
Slowly but surely the world would be reformed to resemble a fantasy like Garden of Eden, where there are not wars, poverty, crimes or diseases.
After another 10 years I would try spreading healing magic everywhere where there are no wars, and at the same time pacify the warring regions.
After 75-80 years in total I suppose that I would've created heaven on earth and I be like some god ( since after such a long time of grinding my skills, level and stats I would probably still live even if I was hit with a nuke or thrown into a black hole) and the people would be healthy, live ecological lifestyle and be happy. And if there were some that would still want to raise hell ( even after being cured of all mental diseases) I would still have mind control skill
