im not rly agree acss
imho best warrior is str int mix
u can make alot more damage with normal damage / magic damage weapon that with normal weapon
becouse u canot put all skill points in str anyway ebcouse magic users will eat u , and magic/meale are 2 most common types of damage in game
if u go int str u got enought resist on str/magic and u got alot of damage if u manage to find good magic/str sword litlle spoiler first best 2 h sword is lord arben sword ( u will be ablle to geet it back) second best sword is "the best 2 h normal sword" or something like that i dont rly know name in english but u can get it as award in wicked wizard cave if u follow path of good this cave is on next part of game . Also the firewall spell is must to for warrior if ur make every quest posible etc cuz u will out lvl enemys on fjords and is rly freeking borring to kill 30 freeking imps who got alot f hp- but make 0 damage to u without firewall
and no u dont need lockpick at all to get rly good items later on u will get nlimited amount of gold nd top tier items in shops so no real problem, but of course its help
most important : DONT TRY TO FOLLOW MAIN QUEST TO MUCH . lvl 7 is much to low to go to tower imho kill all mobs in broken valley make all side quests and if u find out there is no more quests or mobs go continue main quest . dont forgott to explore all dungeons etc :P
peace
