The weather at Giza Plains changes by hour, I think even numbers means rain, or is it the opposite...?

If you haven't already you should check out the upper crystal map on gamefaqs by Seph. It really helps navigating that whole area. Anyways, on that map under the words Map 2 the treasure *can* be the Excalibur, you have to keep walking away, like at least 3 areas and back. Also you have to have the diamond armlet or don't bother you'll probably never get it. Then at the top right, the (T) treasure can be the Zodiac Escthelon, keep doing same as before. Also on that first one, if you get the bravery suit, I think is what it's called, some special armor, then the sword will not show up.

funny thing is i didnt know that larvae eater drops that item so i didnt bother killing them because i was busy looking for the way... anyway guys does the map in the upper right doesnt really work or is it just me?! because the first time i was in the crystal maps i used to see them unfortunately i didnt go there because of my level...now i got 1 character at level 76 and the others are 65+

I never said Yagyu Darkblade was a katana. Going by that strategy guide. Ninja Swords are supposedly more combo friendly than Katana's is what I am saying. But when I used it I wasn't getting as near as many combos as I was with a Katana.
