Swords in treasure chests

[Omnislasher483]

I'm looking for the Excalibur and the Ultima Weapon, i know that the Excalibur is in Giruvegan and that the Ultima Weapon is in the
Pharoah but none of the chests contain them; can somebody tell me what chest they're in and how to get them.

Excalibur

This thing was taken from some guide i found in the net...

Arrive at Giruvegan.
Now go all the way through until you reach
The Great Crystal. This is where the going gets tough.

You start at Waystone (WS) VIII. . Go North-East first to open
the scoprio gate. Then go back and proceed north
now to WS IX, and touch it. This brings you to WS X. Go
down the only path and you'll arrive at WS XX. Now head
down either Southern path to the Sagitarrius Gate Stone.
Touch that and go back to WS XX, then go East, opening
up that Sagitarrius Gate, and to WS XII.

This brings you to WS XIV. Now you have to travel around
to the Excalibur chest. Looking at the map, head SW to
the first platform. North to the next. NE to the next, and
finally NE again to the last. There should be a treasure
chest here, and probably an enemy or two. Equip the
Diamond Armlet and open it. You'll probably get Gil, but
if youre lucky you'll get the Excalibur and youll be done!
However, if you didn't, you have to travel 3 screens back
to reset the chest. That means just count back 3 platforms
or whatever, then return to the Excalibur room. It might
take you in excess of 10 tries. Either way, youll get it, and
a good character can now deal 9999 damage to most of the Great
Crystal monsters with it. Now you can go get the Zodiac
Estucheon.

When opening the chest, make sure you have diamond armlet equiped in a character

Note that, while the chest will respawn, you can only get 1
Excalibur.
