Just a note... Trey and Backstabs leveled up from that last fight.
roll a 1d3 for each stat, and add half of your class bonus (rounding up)...
add the result to each stat, and put your EXP back at 0/100, and change your level to 2... also, Trey can learn a new spell thanks to his higher level. Obviously, he'll have to take it from the black mage portion of the spells list.

As for the few things that happened...
I took a short rest and healed 12% of my HP (3)
I also healed 2 MP

I tried to sneak past the guards around camp: 15 + (7 DEXmod) = 22
Is 22 higher than 20? Yes. I sneak successfully.
I heal Backstabs (at -6/12 HP) Note: She gained a single hit point due to being stabilized for a turn
Healing roll: 2
2 + (11 SPI/2 * 3) = 17
17 - 6 = 11, Backstabs is now at 11/12 HP.
