So I asked my servitors to make an astral object to give to a friend and since I didn't know how the object worked very well, my servitors too didn't seem to know how to do it, and after a while they made it, but it broke apart and dissolved as soon as my friend received it, is there a way to bypass my lack of knowledge and make them be able to craft complex astral objects like electronics, even if I just have a superficial knowledge of how it works?

Do good luck spells cost virtue if we make them and actually benefit from it, like by winning something that would be very hard to win otherwise like in a gatcha, cassino, lottery, or just being lucky in general?
