Does the Bloodstorm Blade have the limitation of Master Thrower? Namely that I have to use specific throwing weapons to get the bonuses of the 'tricks', the one I weapon focused?
Nope. Even lets you treat a ranged attack as a melee strike for the purpose of PA and other things.
"It doesn't matter how much you struggle or strive,
You'll never get out of life alive,
So please kill yourself and save this land,
And your last mission is to spread my command,"
