Iron Helper

It's dangerous to go alone, so take this set of reference cards with you:

(This set of reference cards covers combat, leveling up, equipment, end of level cleanup, facing the boss, and a few other tidbits. There is some redundant information on the combat reference cards, allowing you to swap between them depending on whether you're in the middle of a Skirmish or Ambush)

Better yet, take this double-sided tracker with you as well:

(This little beauty consists of three chipboard tiles held together with rivets. The numbered spaces are indented and sized to fit the included cubes.)

And because you can never be too careful, might as well take these, too:

(This tracker can help you easily keep an eye on your current encumbrance and the amount of attention you've attracted from plot cards. To ensure that you never exceed your character's limit, place 1 of the 10 included cubes on your maximum encumbrance, and then use another cube to move around as needed. The standees serve no in-game purpose; they're there for your amusement.)

Iron Helper is a set of 3"x5" reference cards and trackers (plus eight standees, just for fun) for Jason Glover's Iron Helm that stuffs the rules for combat, end-of-level cleanup, leveling up, boss time, and more into a series of organized boxes with easily recognizable iconography. Additionally, an Enemy Health Tracker easily helps you set up the starting health of your foe before battle, and when it's all over, you can flip it over to the other side and use the Retirement Worksheet to see if you can afford the mortgage payments on that fortress or not.

Iron Helper will easily fit in the game box.
