Int 3 + Stone 3 +1 specialty + 1 dwarf = 8+die
Int 3 + Architect 2 + (1 dwarf?) = 5/6+die
Per 0 + Finesse 4? + 1 specialty = 5
POSSIBLE NEW RULE: "library research bonus" for spending several seasons seeking additional info on Roman Architecture (see "Other People's Vis" thread, on going), from Covenants 98: in this case, +2 "for a Summer Covenant with no particular interest in the matter" or higher, based on how successful she is at acquiring viable research material.
POSSIBLE NEW RULE: Since this sort of Rego Craft effort represents an ongoing effort to work at and refine her project, (as quoted from above, This assumes he does one roll, which is the average of all the rolls he would have made.), then really what we're talking about is applying principles while studying them. So what about allowing a seasons's worth of work to be done in a season as a 7-day distraction from studying, provided that the subject studied is relevant to the craft project (Finesse, Craft, or Architecture)? Possibly even limit it to non-arcane skills.
And before anybody dismisses this as an effort to further pointscum for Finesse levels, I just checked the math, and using the available study materials and seasons, this would only raise me from 4 to 5 -- after I've already built everything for the Tribunal.
Locations
Basic City Grid - the streets, rough building placement, walls, gates
Using well documented city layouts, an extremely simple wall design, with the bulk of the work done by the magically enhanced quarry team, this would be Simple (EF 3) to do, and would constitute a month's worth of work, which she'll try to do in an instant (EF 3 + RegoCraft 3 + Time 3 = EF 9). The big trick here is that she may have to do this earlier than the rest of her efforts, with a lower Finesse score, so her quarrymen have guidelines to work with.
Roman Villa
Roman Style Baths
- City and Guild say that a Carpenter could create 2 townhouses in a season. This is also her first real test of her Rego Crafting skills, so I'd say that she comes out and does a day's worth of effort in an instant every day for a season to make both of these. So it's Base EF __ + Rego Craft 3 = (Int 3 + Finesse __ + safe die roll estimate 3-ish).
Coliseum - that seats 200-300, with loading ramps
- This one is tricky, because I've been directing excavation efforts to create the rough structure of the building starting in 1224.1 (it's partially or completely underground), so the rough shape of it gets done by the quarry team under supervision over several years, with the nobbly bits done by her at the end, the Hermetic equivalent of sanding off all the sharp edges.
Call it an Average Task (EF 9), with a year's worth of work by her, which she'll try to do using both the quarrymen team and her magic in a season. If she manages to find the research material (above), then she may try to get one degree fancier. EF 9/12 + RegoCraft 3 + Time 3 + (Possible Research Bonus 3) = 15
Expecting to have to throw some Confidence points at this. Again, it might be interesting to then limit her study efforts to include relevant topics (can only do this if studying Architecture or Finesse, for example).
Building for Arts and Exhibitions
Actually, I think for RP purposes, we'll say that she cheats on this and will cast two Baroque Peasant Huts with modified designs, and then Rego Craft a month's worth of simple additions in an instant (EF 3 + RegoCraft 3 + Time 3 = 9), because it's a really basic Parthenon style structure. She'll do this in an effort to gain more time to finish "perfecting" the Coliseum.
