Alrighty, going over the characters now...
Bonamius (Voda Vosa):
-XP: 15,000
-HP: Should be 27 (6d6+6)
-Damage Reduction: 1/Cold Iron
-AC: Needs the +1 from the Ring of Protection to make it 20.
-Invocation DC: +4 Cha bonus instead of +2.
Rest of it looks good to me.
Valmun Ourigan (Blarkon Dragonslayer):
-HP: I came up with 21 rather than 22.
That's all I can see.
Jan (stonegod):
-XP: 15000 rather than 21000
That's it.
Brutus "Slim" Carnation (ethandrew):
-XP: 15000
-HP: 33 (6d6+12)
-Spells: Need to select the 4 0-level Bard spells known.
The rest is good.
Victor Rizkad (EvolutionKB):
-XP: 15000
-HP: Came out as 62 for me rather than 66.
Everything else looks good.
Yarra (Legildur):
-Could you post him over in the character thread?

-HP: I came up with 29, not 32.
-Languages: Still have 2 to select.
-Items: No gold listed with the items...but I'll take your word for it with 350g left.
And that's all I can see. I think, overall, the HP changes were popping up because of how it was worded. The even/odd switch is for overall level, so even if you multiclass into something at level 2(and gain the 1st level of the class), you get the EVEN number of HP not the ODD.
Does that makes sense?
Oh, and once we've got things cleaned up and such, we're ready to go. So...will have the IC Thread going tomorrow or the next day...aiming for tomorrow.
