i also like to solo with my fighter. some tips that used to help me,
-always try to only take 1 monster at a time. if you got more, use stun/bone slicer/demoralising hit on the monster you will kill last, so you will take less damage from this one.
-kill monster that give you no curses, wont poison you ect.
-use licences. the more damage you do, the better
-dont be afraid to use many attack skills, mana stones are cheaper then hp ones
-use defence/magic defence scrolls, the less dmg you take, the less you'll spending on pots. use a power scroll if your missing too much.
-dont use vit scrolls if you dont have to. increased max hp wont increase the ammount of hp recovered by stones
-farm herbs, mushrooms if you come across them while grinding
cant think of more atm
