Before to make one Investeed item your own Talisman can't be enchanted with effects by another magiui, but... before of being enchanted on that way could use one lab text to invest one effect on them if the object is capable of be enchanted on that way? After of that you could make it your Talisman?
If I understand what you are asking, yes. A lab text is a guide, not a replacement of your work.
Ok thanks, that was o doubt that i thought.
