if you guys want to see this staff up close there's an npc in the past ( windurst waters[s] ) that has this staff near the HP crsytal. His name is Kayeel-Payeel.
There's also an NPC hume in full PLD relic gear with Excalibur next to a female hume around the taru with the staff as well..
Bet if you look hard enough you'll find other npc's with other relic weapons/gear/ect.
