I've recently acquired a 3d printer and I'm thinking about trying to make some MP-ified condition markers like these.  However, given the flexible nature of powers (vs the fairly fixed list of effects in, for instance, D&D), I'm kind of scratching my head trying to figure out a useful list of conditions that would cover the most common cases without having to get too specific.  "Has to make a save every round to avoid taking damage from Mistweaver's noxious cloud" doesn't fit very will on a 1" ring :).

What would you include if you were trying to make a set of these that was as simple as it needed to be but no simpler?
