I know I'm incredibly lazy but I was wondering could anyone help me find the following weapons in FFXII I have two other requests also.

Excalibur, Dragon Whisker, Whale Whisker, Sagittarius, Formalhaut, Staff Of Magi, Rod Of Faith, Danjuro & Yagyu Darkblade.

Also where do yo get the Zodiac Escutcheon & is there any way to get Genji Armour apart from (SPOILER)stealing it from Gilgamesh because when I tired too steal I kept getting X Potions.
