I tried 4 times . Str 16 Dex 10 Int 10 . I still have 24X gold (can buy 3 Dex ).
I only put in 1 point. The ability to go over walls and through monsters, to extremely freely reposition is just so useful. Can escape from being grabbed, get out if you go too deep. Can never have enough movement. I like how it leaves all your SP for fine manoeuvring instead of any gap close, no need to waste turns waiting for charge.
Play whatever you like, just a recommendation for even more fun :)
