Masterwork

For every additional 50% of time is spent creating an item, the crafter can improve the quality of the item by one unit. Each of these units is called a Masterwork Unit, or MU.

Because cost is a result of the time spent crafting, each MU increases the price by half of the original. An item with 4 MU would cost three times what a normal item of the same kind would cost.

Improvements

Improvements are designated by three factors - first, what the base improvement is. Second, how many MU it requires to make this improvement. Third, what the maximum amount of improvement may be in this area.

General

General can be applied to any item not in the other categories

Base	MU cost	Maximum
+1 to hardness	1	+2
10% less weight	1	50% less (five times)

Weapons

Base	MU cost	Maximum
+1 to attack	1	+2
+1 to damage	1	+4
25% less weight	1	50% less (twice)

Armor

Base	MU cost	Maximum
+2 to hardness	1	Once
1 less Armor Penalty	1	2 less
10% less weight	1	30% less (thrice)

The bonus against Armor Penalty only applies if the armor is fitted to the character. Masterwork armor with this quality is fitted to a specific person at creation, but this may be changed with a craft check of 10 less than the check to create the armor and 1d4 days' work. Masterwork armor that is not fitted to you does not gain this benefit.

Shields

Base	MU cost	Maximum
+1 to AC	1	Once
5 lower arrow block DC	1	Once
1 less Armor Penalty	1	Once
5 lbs less	1	10 lbs less (twice)
