Sureyoucan, but i wouldn't help you..... . Your Hero is already a very physical. It is more helpfull to invest everything into Strengh.
If you plan to impress the People of Gudan, you would need ten (10) Agility to impress Jorgen and catch the bunny. Do you also care about impressing rasmus with the eight (8) Int check while reading the book? With your state now, that goal is not possible anymore., unless you still got a huge amount of unsuesd Adv and LvL Points.
So i rather recommnd:
A) to press on with the game, have fun and invest Points into Strengh, so Eyvind can easily break free from Grips (Yeti, King-Slim) and beat the shit out of everyone. Leave the other stuff for another Playthrough.
B) Buy one or two incense burner from Chet, and adjust your stats. (make sure to unequip all items before using it). So, once the game allows you to level to 25, but before going into the Snow Area, you could farm exp and tones of money to buy the incense burner. You can do this while Perith is away during Thanes Hell kitchen Quest. The special dish at the end of this Questlines give a few Lvl Points.
Whatever you decide, mke another safe save, before you follow through.
