[MH] Quick and Dirty Charm Rules for Spells?

[PK]

I've never used them outside of downtime, myself. But yes, the math behind it holds whether it's for charms or normal rituals -- if they're being cast in a controlled environment, and time is completely not a factor. For an adept, I'd say you should have at least half an hour free per ritual; for a non-adept, at least half a day.

Also, the GM should realize that boiling a dozen or so rolls down to just two means that Luck and unspent character points or destiny points become much more of a factor. The stated assumption, that you'll only be using these rules during downtime, means that's not much of an issue -- the rolls are compressed for that purpose, but so is time. But if you're letting casters do it in game, you may need to forbid the use of Luck/points on these rolls. You may need to try it and see how much of an issue that is.
