Despite how curious Eldrian was about the process of evolution, he had let Vrisky use his laboratory alone. Evolution was simply too dangerous to not take precautions. The same could be said for Creation. Hence he had invested nearly everything he had into making his. 

'I was really shocked when I learned I could make mana crystals with Creation...' That discovery was what had allowed Eldrian to gain enough mana for a magic Crystal.

By using his mana excess to make 'batteries', he was able to gather the required minimum amount in the past few weeks. It was a bit more complicated, and he couldn't make an optimal amount to use all his mana—normally he could only manage three crystals a day. But it was still better than nothing.
