Lith and Solus had no such problem since they had the same energy signature, but for any other mage, it was the only way they had to craft powerful artifacts with the help of one or more colleagues.
It was also how the fake mages of the Kingdom had enchanted the six great Academies and how Inxialot's Adamant sphere had been capable of empowering the golems back in Urgamakka.
The sphere itself was a teaching tool, showing to whoever was smart enough to understand its workings how to properly arrange different pseudo cores and how to align their common runes.
Lith had decided to start off with ten pseudo cores while Solus would add five more, but he soon noticed that they needed a change of plans. The strain from keeping the world energy in the circle and outside the staff already took too much of her focus.
Any more and she would not be capable of participating in the Forgemastering process.
