I remain with a question that I cannot really find an answer to.
I finally have my lab at level 5, ranking up my monsters to lvl 5. This means i get my uncommons, commons and rares to lvl 5.
Now i would like to know if it had any valur to keep these monsters now, as in, can I extract them (or sell them) to get more space on my islands, is isnt that recommendable?
