Dynasty weapons.

Winner!
Did you collect all 25 weapon types, or not?

It's impossible to collect them all. I collected the ones available in the campaign, except for the Orcish sword, Tears. I received the Staff of Purification and the Staff of Eight Aspects of Ashi as a collector's item, and also unlocked Oblivion for yuPlay points. And, while the Inferno campaign shop was still open, I got the Blade of Chaos. Moreover, I think I haven't bought all the weapons in the shop yet.
