Virtual Combat Cards (VCC) is a tool designed by Dungeon Masters for Dungeon Masters. Designed to be simple and easy to use, VCC will help you track several aspects of your D&D 4th Edition combat encounters.
VCC is free, open-source and multi-platform.
ScreenshotCool new features coming in version 1.0
Time for a little foreshadowing as works progress on version 1.0. A lot of nice features are on the way, to state a few:
You can now store your monsters and assemble parties quickly (it even helps you with the XP math). This is due to a completely new file format and data structure.
D&D Insider Capture: This combines a Firefox plugin with new VCC features that will allow you to automatically get all the relevant information and the stat block into your collection of monsters.
New interface that shows the stat blocks. Gone are the days of having 3 source books open, or 6 tabs on your browser pointing to different monsters. You can have it all in VCC!
Spoiler
I haven't used it - waiting for statblock inputs... but this looks to do a whole lot I'd love to see MapTool do by itself. Hellllllooooo 1.4 =)
