Don't worry, i got platinum without playing online, so you'll be able to as well. True, the bladestone trophy is probably the hardest of all the stones trophy's, especially because of the rare pure bladestone. But in world 4-2 (behind the secret passage - close to the primeval demon) there you'll find a black skeleton that'll drop a pure bladestone after a while. Black World Tendency is adviced though.

after a while?! YOU LIE!!! >:(

After 10-15 tries he dropped a pure one. I carried the large sword of searching with me, though.

Why would you need the swrod of searching? Waht does it do anyway, increase the rate of rare drops? Or is it like a radar?
