So, anything made of Steel is likely right out.UNITS OF TIME REQUIRED FOR CRAFTING
Material:
Steel Zeni: - Bu: Days Koku: Weeks
Metal/Glass Zeni: Days Bu: Days Koku: Days
Other Zeni: Hours Bu: Days Koku: Days
TIME UNITS NEEDED BASED ON PRICE
Zeni Price divided by 10 in units (minimum 1)
Bu Price divided by 5 in units (minimum 1)
Koku Price divided by 3 in units (minimum 1)
DIFFICULTY OF CRAFTING ROLL Zeni Bu Koku Costs
Costs 1-10 zeni: TN 10
Costs 11-25 zeni: TN 15
Costs 26-50 zeni: TN 20
Costs 50+ zeni: TN 25+
Costs 1-10 bu: TN 15
Costs 11-20 bu: TN 20
Costs 21-50 bu: TN 25
Costs 50+ bu: TN 30+
Costs 1-10 koku: TN 20
Costs 11-20 koku: TN 25
Costs 21-25 koku: TN 30
Costs 25+ koku: TN 35
NOTE: For each increment of 5 above the final listed cost, increase the TN by 5 as well.
40 zeni
20 bu
and
12 koku is probably the upper limit on costs, since that would take 4 days. (You can't convert stuff, if it's listed in the book as 10 bu, it uses the bu table)
