Alhaitham Best Artifacts

According to lots of banners' tests and the data from the servers, no matter whether we build Zhongli as a DPS or a Support, we should focus on:

Elemental Mastery %
Elemental Mastery
Crit Rate
Crit DMG

So I suggest using:

Basic (Obtaining difficulty is low, only for transition):

2 EM + 2 EM Set+ 1 Free (Elemental Mastery / Crite Rate)

Middle Set: EM or ATK
4th: Dendro DMG > EM
5th: Crite Rate > Crite DMG

Better:

4 x Gilded Dreams + 1 Crite Rate

4x Deepwoods Memories +1 Crite Rate

Artifacts

Gilded Dreams

ATK is increased by 14%, and EM is increased by 50 for every member with a different Elemental Type. Each of the buffs will count up to 3 characters. This effect can be triggered once every 8s and even when not on the field.

Best Weapons

For choosing his weapon, we should focus on Elemental Mastery and Crit DMG / Crit Rate.

Weapon	Obtain	Details
Harbinger Of Dawn	Wish	Both stats are Crit DMG. It can provide the great DMG. This weapon is good for the beginners. However, this is only a 3-star Weapon, only for transform.
Iron Sting	Craft	This is the best 4 stars weapon for Alhaitham. It can provide the ATK and Elemental Mastery.
The Black Sword	Battle Pass	Can give great Crit Rate. When it in level 90, it can provide 27.6% Crit Rate. Use it when you have a Crit DMG Head of the artifact.
Toukabou Shigure	Event	Provide the EM and ATK, also a good weapon for Alhaitham. However, I prefer to use this weapon on Kuki Shinobu.
Light Of Foliar Incision	Wish	This is the best 5-star Claymore for Alhaitham. It has high EM and high Crit Rate on it.

Best Team Build

There are many ways to build Alhaitham's team. Here I only give some popular examples, which are useful to beat the monsters in Spiral Abyss.

Super Bloom Team: Alhaitham + Xingqiu+ Yaoyao+ Raiden Shogun


Alhaitham	Xingqiu	Yaoyao	Raiden Shogun

Bloom Team: Alhaitham + Xingqiu+ Yelan+ Kuki Shinobu


Alhaitham	Xingqiu	Yelan	Kuki Shinobu

Quicken Team: Alhaitham + Zhongli + Yae Miko + Nahida


Alhaitham	Zhongli	Yae Miko	Nahida

Here you can know, Alhaitham or Kazuha, which one is better to get?
