Home Brewed Side-Effect Virtues and Flaws
Weird Laboratory Student (Minor Hermetic Flaw)
Despite having clear and easily identifiable instructions, sometimes things just don't work out the way they are supposed to. When working from a lab text to recreate a spell or to create an item, you roll on the Side Effect table in Experimentation Extraordinary Results. If creating multiple items or reinventing multiple spells in one season, roll separately for each.
Design notes: The side effect table is nominally 40% neutral, 40% bad, and 20% positive, though some of the neutrals can be considered a negative at times and one of the rolls is really bad - arguably a seasonal waste. So this is probably too much of a flaw. But I know people who would take it anyway.
Calculated Experimentation (Minor Hermetic Virtue)
While the experimental process is dangerous and profitable, some people have an ability to minimize the risks for some rewards during experimentation. During any laboratory activity where you would be allowed to experiment, you may instead select a flat +3 bonus to the lab total, in return for rolling on the Side Effect table in the Extraordinary Results chart. If you have a Magic theory of 6 or higher, you can also select a +6 for two rolls; With a magic theory of 9 or higher, you may select a +9 in exchange for risking three rolls on the Side Effects table. This cannot be used when experimenting.
Design notes: The reason this isn't used when experimenting is thematic, not because of game balance. I was using Inventive Genius as a baseline to compare against.
Hasty Researcher (Minor Hermetic Flaw)
Perhaps its impatience, or perhaps its an inevitable cutting of corners; Either way, you find yourself getting work done a little faster, but who cares if there's a few odd side-effects now and again? Whenever doing work in the laboratory on anything that would allow experimentation, you get a +2 to your lab total but must roll on the Side Effect table in the Extraordinary Results chart.
Design notes: I felt that the required nature of the flaw made it too hurtful without a small bonus.
