Tracking the hit points of Heroes and their foes is a critical part of gameplay. It needs to be a simple, quick process, and it needs to provide immediate visual information on combatants current health.
Until a couple months ago, I'd been doing this with health tokens in denominations of 1, 3, and 5. This posed multiple issues; it was fiddly, took too long to upkeep every round, and to "read" a combatants health you had to tally coins and do a calculation.
It also made it hard for Heroes to know their allies health without asking them, then waiting for them to tally, calculate and respond. This was especially bad since round by round combat decisions want to be informed by the Heroes health states.
Thankfully, an astute playtester presented a better solution, and the health track was born! Much like a VP track in other boardgames, the health track is a common strip of values where all Heroes and Monsters track their health with different colored discs. In the middle image above, you can see it in action, with Bren's black disc, Sil's blue disc, and a single Monster's purple disc. This way, tracking health is fast, all the values are readily legible, and you see their relationship to each other at a glance. Brilliant!
