Basically, this 2-page sheet helps me handle 3 critical things during a game session:
1) It allows me to see important player character stats at a glance and track damage/conditions/etc.
2) I can jot down notes on encounters the PCs have, treasures they find, and track their accumulated expees.
3) It gives me a place to write out monster stats so I don't have to flip through a book unless absolutely necessary.
Enjoy, I hope you find it useful!
