There's no need to even think
all you need is the last promotion, then every stat goes into vitality ( HP ). If you use Db after ur last promotion, then put 2 on dex, 0 spirit, 176 str, everything else in vitality
)
If you ask why:
1 strength = +1 dmg ( no point in that ) ( 176 strength for using weapons 1-130 )
1 dex = a bit more hit rate ( u will just depend on skills like rage, phoenix... or on fastblade/scentsword ) ( 2 dex is minimum u must have O_o ) ..
1 spirit = 5 mana ( you don't need mana at all )
1 vit = 54 hp ( the best part and look if you get like 50 additional vit you get 50x54=2700 more hp !! thats awesome! )
I think you should be able to have about 10k hp if you use the db and get what i said... You should have about 200 vitality
