Epiphany!
I was minionizing the deathjump spider from MV1, and wondering what to do with its 'death from above' recharge power. Obviously this power is largely what makes the deathjumper a skirmisher, so I don't want to just drop it. But I also don't want to be tracking recharge powers for a horde of minions.
Then I thought
why track recharge powers, especially since they usually get used the same round they're recharged anyway? So I've invented a new type of power: the 'use or lose' power. For example, the minion deathjumper's 'death from above' says 'Usable on a 4, 5, or 6.' Meaning that the power is either usable or not usable on any given round, depending solely on a d6 roll. Use it or lose it; no saving the power for a later round. I'll probably roll a d6 for each group of 4 spiders...except maybe the first time. Rolling two handfuls of d6s right in front of the players tends to have a pleasing effect on them.
So what do you think? Brilliance, or something that you thought of years ago? Now that I've thought of this, it feels too simple to be original so I'm honestly not sure.
