In Numenera, wearing armor with which you aren't trained causes you to spend Might points (pg.81 Core Rulebook) each hour. While all glaives start with abilities that mitigate part of this cost, nanos and some jacks may not.
At my table tracking this Might cost is causing problems. From the storyteller's side, most of the time I completely forget it. However, I suspect it's actually an important concept from the storytelling perspective - it causes players to think about when they are wearing armor.
When I do remember, tracking time seems like a book-keeping chore. I have to consider how long the players have been in a dungeon, how long they track beasts across a wild expanse, etc.
How can I better track Might loss due to wearing armor?
