if you didn't make any items, you should have 210,000 XP. The extra 10,000 XP he gave us was only for the purposes of making items, he said we loose any of it we don't use.
So, if you're not casting any permanencies or making any items or epic spells, then you just loose it.
BUT, here's a cheap little thing u can do with it if you know Wish...
Wish spells cost 5,000 Xp.
Therefore you could use that extra 10,000 (which will go away whether u use it or not) to cast 2 wishes, and basically do whatever the f*ck u want with those wishes... I'ld personally use them to either grant a free +2 inherent bonus (Such as from a Tome or manual) to a stat, or to create two valuable/magical items of up to 15,000 GP each.
Alternatively you could do the following (Which I HIGHLY recomend)
Use Wish to duplicate Rary's Telepathic Bond with one of your fellows, then use another wish to make it permanent (Rary's Telepathic bond says a Wish can make it permanent between two people).
OR, If you(Or any of us) actually KNOW rary's teleathic bond as a spell (or have/buy a scroll of it), you could use two wishes to make it permanent between three people.
That's permanent 3-way telepathic communication....
