Where can I find a Solari crystal, Upari crystal, freyyr's war blade, and..

It's different each time you play. Usually, though, by the time you're on the Ravager, you've found those items, or else you can't find them that game. And by "by the time you're on the Ravager," I mean sometime while on the ship. I remember finding Freyyr's Warblade and the Arg'Garok deal there. As for the crystals...I found like 4 upari's once. I've only ever found a Solari once, though. And, lucky me, I was a Dark Jedi, and so were all my companions (since I'm so influential). Meh. Maybe you have to be on the Dark Side to find a Solari crystal, and then you can turn back over to the Light to unleash it's awesome might...or something to that effect. ;)

You can do it.

You can find a solari crystal on Onderon in the cantina. Find the blonde girl with blue clothes.She will want an open starport(if you don't have one ask Kiph(Green twi'lek)to slice the bounty hunter's.)Give it to her and she will ask you if you want a weapon,some credits,or a lightsaber crystal.Select the lightsaber crystal.(Note:Can only use if you are a Dark Jedi)

The crystal you get on onderon in the cantina is a quixi crystal not a solari!!!

I didn't know till it was to late.

All of the items in the game are completely random that are in corpses, remains, ect.

(Some special items are set though). So there's no way to exactly tell when or where they appear.

Well I found all that stuff,plus more in the Trayus Acadamy!!!Most are random though andyou find a whole lot of crystles there to.If you don't find a Solari you wont find one again.
