just made one to see what it was like
2 small bricks of velium- about 14pp each when I found em at a vendor
+1 coldain velium temper 25pp
= velium sheetmetal
add daggerblade mold 2pp
add hilt mold 1pp
add pommel mold 1pp
(especially frustrating since the last patch made these no longer available in freeport)
add another coldain velium temper 25pp
so about 85pp in materials
pretty quick weapon damage all depends on how often it procs
