Ultima Sword and Excalibur ~ HELP!!!

Hey~!
I want to know where I can find
Excalibur and Ultima Sword of Steiner
Help me, please ><

Excalibur — you need to purchase the Magical Fingertip from the Treno auction. Once you have this, there’s an old man in Daguerreo who asks for it, give it to him and you’ll get Excalibur.

Ultima Sword — Daguerreo again, purchase from the weapons shop, but only on Disc 4. Or just steal it from the boss Maliris.

Buy the rest of the key items from the auction house until the Magical Fingertip appears.

Aiming low I see, why not go for the infamous Excalibur II challenge?
