Yes, if it have good stats you can even use it at higher AR, because farming good 5* artifact is a long process. Though some specialize artifact are only available to farm at higher AR, so don't spend too much time and resources on lower AR artifact. You mainly only need to level the artifact that your main DPS uses.
Yes it's good, just bear in mind that there is no guarantee in getting it from the weapon banner.

Below is a good comparison between spears.

No matter how good a substats is, upgrade process can still ruin it.

Example you get Pyro DMG % already.

Substats
ATK
ATK %
CR
CD

RNG can just give you flat ATK or CR that you don't need.

I suggest get Hu Tao first, as you can see Deathmatch is a pretty decent weapon and doesn't need a lot of money to get. Also low investment since it's good at R1.

She is not like Diluc at all. She's way better than Diluc lol

According to Honey hunter her base attack at 70 is 81. So I guess not a bug, she is just like that.

yep her main weakness is this

That's why I feel she need Homa to cover for the lack of ATK. Don't feel its worth building her without it.

tried her E? with ~30k hp that'll will dump a ~1500 atk onto whatever you have, that's pretty damn crazy. with weapon and artifact you can reach 3k attack ez

my Hu Tao have 28k hp using Deathmatch, all talent level 1, charge atk during E is 8.8k, melt burst highest I manage to hit is 77k on Childe.
Crit rate 61%, crit damage 192%.

She rely on her E and Q for damage, without it she hits like wet noodle.

yeap, running crimson witch set. I forgot to mention that I uses food for Childe. Currently my Hu Tao have talents at 6 6 5, 58% crit rate and 212% crit damage, she can hits 88k on melt without food at below 50% hp.

No it's worst than even White Tasset which is a 3 stars spear. Skyward Spine simply doesn't do anything for her.

What other spears do you have?

Congrats. Mona not suit to pair with Eula. If pair Ganyu freeze comp then suit. Eula's freeze too short lol she's more of a physical attacker.

How are you playing your ganyu?
If it’s in a freeze team, can continue farming blizzard strayer.

Throw all your resins into the new Sumeru artifact domain.

It'll be relevant for a very long time.

Alternatively, Thundering Fury & Thundersoother is also great on Aggravate DPS e.g. Keqing & Yae. There's Cyno, but you just missed him.

If you wanna play something new without much effort, Nilou's your best bet. 9 days left on her banner.

She can 36* Abyss without any proper artifact sets, weapons & talents.

OK. I buy 2 years welkin first.
