I was wondering to begin my new game with a tosser, so i looked for the stats/trait i need in order to get a good tosser, but i read that throwing is based on strenght, but while i was creating the char, i noticed it's based on dexterity. Now, i'm a bit confused: i want a tosser that's able to throw knives(expecially the throwing-master's weapon) and that's able to throw bombs (then i need at least 9 in intelligence; i can save 10 points using the intellect potion to reach 19 and unlock the other schematics, although i won't be able to use them without manuals or after the potion's effect has gone), but i don't know what stats i have to maximise, and what background would be the best; i saw the knives tosser one, and it adds 2 ranks of throwing, but i read that the backgrounds that add ranks to skills are useless because you'll have to spend 5 points the same. Then, what do you suggest?
