If you want to main warrior and secondary fighter go str then will ... if its vice versa then prioritize will over str. CP shouldnt be an issue anymore but WM is still top priority imo. All str/will [even luck] life skills should be ranked whenever possible and can be trained passively at any time.

Stage 1
r1 WM, r1 Refine[can be skipped], r9 CM, r9 SM, r9 Smash/Assault passively rank Crit
Stage 2
r1 SM, r1 Smash/Assualt, r1 CM, finish up crit if possible
Stage 3 [optional? ... if your going to skip this rank it eventually for the str]
r1 Range attack, r1 AR [to use for rafting?]
Stage 4*
r1 Mining, r1 Carpentry
Stage 5
r1 Blunt Mastery, r9+ Charge, [r1 Counterattack, r1 Defense ranked for synergy with skill set]
Stage 5
r1 Lance Mastery, r1 Lance charge, r2 Lance counter

After this, its just amassing leftover expensive str or start fighter.

Stage 6
r1 Charge, r1 FH
Stage 7
r1 All fighter skills
Stage 8*
r1 Hoeing/Harvesting/WineMaking, r1 Rare Minerology/Engineering, r1 Magic craft, Rest, Fishing, Trans Mastery
Stage 9
r1 Guns [Everything but way of the gun] or Puppet [Everything but wire pull/snare and Act 1]

Other then this, you still hav Blaze/Fireball/Thunder, Magic Shields, Bard Talent, Hidden skills Assorted amount of will skills that can be slotted in anytime you want after fighter get maxed.

*Remember, dont take everything literally, this game is 'fantasy life' and should be played however you want. If you rather ranked one skill set over the other first, you can. If you want to mixed and max and focused on one over the other it still possible. Just rank those that seems easy for you, push back the ones that are too expensive or too tedious for a later time*
