Krug: Okay. You need to make a Use Magic Device check at DC 21 for each of those —
[Cure Light Wounds, roll of 8 on d20, +9 skilled, total 17, failure]
[Cure Light Wounds, roll of 8 on d20, +9 skilled, total 17, failure]
[Cure Light Wounds, roll of 16 on d20, +9 skilled, total 25, success]
[Enlarge Person, roll of 13 on d20, +9 skilled, total 21, success]
End results: You create a potion of cure light wounds and a potion of enlarge person, each at caster level 1. The cost ends up being 50 gp and 5 points from your craft reserve, which then resets itself to 40 (for achieving second level).
