After using your reference sheets for several months now Printable Reference Sheet, I thought of a few suggestions based on what I ended up adding to the printout.
On the Kingdom Power Checklist, a box to check off if a player has obtained the Hero Class Weapon in the Hero Class section.
A Faction Checklist or some sort of checklist for players to know if they have obtained all the troops for that faction.
In the Quick Reference Tables, a table that shows the weapon the Talent Tree correlates with. For example, Cunning = Dagger. I printed out the Hero Classes Reference Table and added my own table to the back of it. Embarrassingly, I did not realize for quite awhile that a weapon correlated with a particular talent in the tree.
Once again, thank you for all the time and work you put into this, I reference my printout almost everyday for months now and has been such a great help to me!
