These cards are designed to be printed on 4x6 index cards. To make them reusable, put clear tape over the HP, Ammo, and Spells areas (all in the top right), then use a dry erase marker to keep track.
Couple of notes:
I factored "Versatile Performance" into all of the skill blocks for the bard at the end (the published stat blocks did not).
I also fixed a stacking bonus issue with the 6/7 bard (Headband of Alluring Charisma / Eagle's Splendor). If you'd rather use the original you're of course allowed to do so, but you'll need to use the published version when you get to that badguy.
Those who don't know about it should definitely check out
TheGM.org for spell prep. I've asked the webmaster if I can upload spell cards for the spells used in this scenario, but I haven't heard back yet. Either way, click through and create spell cards for the scenario!
