Here is the final count of experience for the party.
In addition, for objects found on the creatures, add 143 for Embla and Lothar, who don't receive an x.p. bonus, and 157 for Engelhart and Pandred.
This puts Embla and Engelhart both up a level. I don't know if it gets Pandred there. Lothar, I know, doesn't make it.
I'm going to work, but Embla should roll a d8 for hit points, as should Engelhart. Engelhart, you gain a 2nd level spell at 3rd level, plus 2 bonus spells from your wisdom. Therefore, you should choose three spells from this list.
This is all I have time for. We'll sort out sage abilities when I get back. I'm off work again tomorrow, so we have time to make sure everything is accounted for.
