For mages, skill level does not matter, except for SP and classes. Unlike for swords and guns, you can just leave magic at 90 if you want.
For stats, int and dex are the only ones that will increase your damage (str and quick if you’re hitting with a normal attack, but those don’t really matter). Up until 305 dex, it is likely that a dex point will increase damage by more than an int point.
Yea quick and str doesnt matter much. I’m lvl 90 and doing well with 300 defence and might go lower (int is over 500 so idk quick points are nothing) strength 1% doesnt add much to survivablity and adds about nothing. I think dualdoc got it right.
The only reason to up those is to get a more balance stat base to gain maximum lp/pill
