Without using any Level F Stamina Restorative Potion, each of the 15 shadow clones could use Sparks about 60 times on average and directly increasing the proficiency of Sparks by 900.
This wasn't even the limit.
If it weren't for Sparky using dual thinking, with part of its focus on the TV, which drained its mental power too much, there might have been room for even more proficiency increase.
Riley suddenly had a thought, and the Beast Tamer Codex automatically flipped to the page about the Little Cosmicub.
[ Level: Beginner (255/1000) + ]
The Little Cosmicub was different compared to Sparky.
Probably due to its high talent, it gained 3 points in level every day automatically, while the Mystic Gemstone added 5 points just like the Flame Gathering Pearl.
