Hey, crafting this thing is giving massive amounts of exp for the cost of the materials. On the TP it costs roughly 3-4 sil each. To create an equivalent item costs 8 silver minimum for the 8 potent venom sacks, this is excluding the cost of silk bolts for the pattern parts.
I went from 363 to 383 skill with 10 doubloons which would have taken me at least 15-17 patterns completed. Imo, double the doubloon cost on this.
