Hmm, I never realised my maths was so bad....
I am trying to make it so that every 1-6 years something interrupts the normal routine of lab-work. This event may occur in any season and last 1-4 seasons.
This is easy enough to do with a D6 and a D4, but then I have other things - like consequences - XP, injured, Twilight, loot etc.
As my magus is a Verditius, I am also planning for him to receive the occasional commission which will distract him from his work but generate income.
Now to drag it to a D10 AM based system...
Each year roll a stress die, add the number of years since an adventure. If it is greater than 9 there is an adventure, if not, proceed as normal.
Adventure, roll a simple die, 1-4 is one season, 5-7 is two seasons, 8-9 is three seasons and 10 is 4 seasons.
Roll a simple die for the adventure result, 1-4 nothing. 5-7 light wound. 8-9 twilight. 10 heavy wound
Roll a simple die for the XP. 1-8 is adventure XP, 9-10 exposure.
If not adventure...
Roll a stress die (no botch) + hermetic reputation
<9 nothing happens, 9-10 open an item, 11-12 Lesser Device, 13-16 Greater Device, 17+ roll twice on the table ignoring 17 or more.
if Greater Device, roll a stress die (no botch) if 1-6 takes one season, 7-9 takes two seasons, 10+ takes 3 seasons.
To calculate fee for device roll D5 for technique and D10 for art. Add the scores together and round down, then multiply by 3/4 to get amount of vis earned.
If Opening device, Fee is Stress Die * 3 VIM vis.
Have I missed anything?
I am planning to have a computer program generate this list of seasons and I will then work his studies around them...
