so i had the most fortunate turn of events happen
okay so i had security shades, and had a problem selling them.
this guy offered me a chem set for it, it was a villain's veil strangifer. The recipe took 7 normal weps and a strange bonesaw
i completed the recipe and proceeded to sell the tool on the market :)
btw why do chem sets make 5 ref items 3 keys more? if you find the right one, it's easy.
