Hi my friends <3
Maybe you don't know!
Artifact Level 86 can be refined by both Artifact Level 8x and 9x.
Level 9x stage, Artifact Level 88 is the best choice . All stat in Artifact Lvl 86 higher than all stat in normal weapon.
Now, Let's go! Make yourself a GOD WEAPON <3
Note: All stat will be random. You can use Artifact Spell re-refine it.
