Thx anyway but I got that quite a while back
As for the Saturn Crest, that got me too.If you have checked Mount Gagazet(where it actually is)are you looking in that area just after the mountain near Zanarkand? Thats what I did for ages and It isn't there.The best thing to do is go through the mountain from the start with no encounters and eventually there'll be a save point on a slope.Keep going up and around and there'll be a few pillars.One of the ones on the left hides the chest containing the crest.
UPDATED LIST THINGS I CAN'T GET:
Venus Sigil ARGHHH 139 is still my best..... or did It go up, I can't remember but I think i got 160+ once
Saturn Sigil Whatever, I dont use Kimahri I only got the crest and weapon for Ixion Break Dmg Limit.
THINGS I CAN GET:
Sun Sigil:Easy
Jupiter Sigil:Again this was easy
Mars Sigil:Not easy but I did it....
Moon Sigil:Hurrah! I removed a certain problem(Dark Valefor) And I was well on my way!
Mercury Sigil:For that silly Cactuar in that hole I had to kill Dark Ifrit to make him show up.I don't know why that happened.
EVERY CREST + WEAPON-Hurrah! But at the time I didn't have the Saturn Crest.I forgot to mention it
