Alright, I have edited the XP count for the party. You are now more than halfway to level 16! Huzzah!
I also took the liberty of adding an extra piece of magical treasure. Vertasi's boots, as it turns out, are magical. Unless Medinah or Amirah wants to wear them, you may want to transfer the enchantment to boots that don't have stiletto heels built in.
