How do weapon cost modifiers interact?
Let's say I want to buy a Snowgarden Productions tactical starknife.
That's 110 base, for the star knife times 1.1, for the extra 10%, is 121.
If I want an adamantine alloy tactical starknife, that's 110 +2,500 for the material: 2,610.
What if I want an Adamantine allow Snowgarden Productions tactical starknife?
110 * 1.1 + 2500 = 2,621
or
(110 + 2500) * 1.1 = 2,871?
