I'm thinking about homebrewing something that will allow a melee warrior to make his attacks at range. It's a common trope in games or anime where a warrior is so skilled with his weapon (most often sword) that he's able to make attacks at range by using wind force/sonic wave/some kind of ki energy.
What would be better - a feat chain or a prestige class?
I retooled the Brutal Throw feat (Complete Adventurer) to be a bit stronger. Granted, it didn't put in the Throw Anything or Returning properties in, but I did allow Power Attacking and charging with the ranged attack.
Brutal Throw [General]Prerequisite: Strength 13+.
Benefit: When throwing a weapon, you may add your Strength modifier to the attack roll instead of your Dexterity modifier. The range increment for all of your thrown weapons doubles when you do so.
In addition, you may Power Attack with a thrown weapon, treating it as a one-handed weapon for purposes of calculating the bonus damage. You may also throw a weapon at the end of a charge, and you gain all of the modifiers associated with a charge on this attack. You must throw the weapon along the same line that you charged.
Special: A fighter may select this feat as one of his fighter bonus feats.
So, to answer your question, I'd say "a feat", unless you're looking for something along the lines of the Bloodstorm Blade PrC or something. Honestly, I don't even feel that PrC should be a 10-level class. It's not giving you anything that is a level 15 ability.
