The 4.0 Update seems to also have new Strongbox Artifact, which I am looking forward to.

Can't be used to get more of any set you actually might need, nothing from pale flame set onwards.

you can unlock this at AR 45, y’all forgot to mention that!

okay so what ar level can i do mystic offering im at ar 43 right now and its not accessible to me

Stop yelping everyone! It is clear that such a system is not a game changer by the way

Literally my first aritfact converted is a bloodstained flower with 36 crit damage. Thank you Mihoyo

I have multiple artifacts to use for this and it won’t let me.

1 crit rate helm bad substats , 1 atk sands no crits as substats , 1 DEf cup Useless. , after sacrificing 9 5 star artifacts that i could have used as artifact upgrade fodder, RNG as always , .. your milage may vary

Just converted about 60 artifacts into Noblesse Obliges with great DEF and HP stats. That's just not what we need, Mihoyo!
