Shadow Creature

The difference between shadow creature and shadow legion was that shadow creature had no immortality buff.

The shadow creature could die because of light element while the members of the shadow legion would technically exist as long as the Lich still has mana. They would never die and would recover quickly. 

Inspecting the shadow creature, Riya found that the shadow creature had died.

'In that case….'

The runes moved and a magic core was taken. There were not many magic cores that Riya had gathered so far because the number of rank 1 magic beasts were limited. She tossed these cores to her world but forbid her world from absorbing them.

She could make a good use of these magic cores in the future. 

And the magic core in Riya's hand was a rank 2 core, which meant that this shadow creature was a rank 2 magic beast.
