I'm thinking of making a Bloodstorm Blade that pulls off an equivalent of the Creation Slaying Oblivion Kick combo in Exalted (basically, it let's the character attack anyone he/she can see, and then throws on an effect that allows them to kill people with a touch).
Thing is, I can't think of any really broken combos to pull off using the fact that Bloodstorm Blades treat ranged attacks as if they were melee attacks.
I know that they can do Deadeye Shot+Shadow Blade+Hit-and-Run Fighter to add 3x their Dexterity modifier to the damage of their thrown attacks, but that is kinda weak-sauce (though this does mean that they are pretty SAD, combat-wise, only needing Dex and Con.)
Another idea is to use Teamwork Benefits to allow you to treat people being hit by your throwing weapons as if they were flanked... which is great for sneak attackers.
Any other neat spells, cheap templates, feats, or other effects that restrict their functioning to only working on melee attacks or ranged attacks? You can also include class feature that can be obtained with a dip, but nothing further in than, say, 5 levels in a class.
