leggoboyo more like Mr Dr Leggo Boyo

I had killed Ekimara and was looting then Leshen stomped in.

i was fighting againts the ekimmara and when i killed it Leshen appears, and then i took everything that i could find in the area(even griffin diagram) and ran out of the cave xD, anyway i still want to kill the Leshen too but im level 6, there is any chance , any tip that you can give me and its worth it?

on mine game they both just fought me not each other. uploading it now.

This all looks really cool inside this dark cave, especially when the leshen fades.
