Best Artifacts

(2) Increases Elemental Mastery by 80.
(4) Within 8s of triggering an Elemental Reaction, the character equipping this will obtain buffs based on the Elemental Type of the other party members. ATK is increased by 14% for each party member whose Elemental Type is the same as the equipping character, and Elemental Mastery is increased by 50 for every party member with a different Elemental Type. Each of the aforementioned buffs will count up to 3 characters. This effect can be triggered once every 8s. The character who equips this can still trigger its effects when not on the field.
Gilded Dreams provide a lot of ATK and EM buffs that benefit Alhaitham's damage. Best option if there's a Deepwood user in the team for Dendro RES shred to further boost damage.
(2) Dendro DMG Bonus +15%
(4) After Elemental Skills or Bursts hit opponents, the targets' Dendro RES will be decreased by 30% for 8s. This effect can be triggered even if the equipping character is not on the field.
Good option if you don't want to rely on another teammate to use Deepwood and allow Alhaitham himself to inflict Dendro RES shred. Plus the 15% Dendro DMG Bonus in the 2-piece set effect is also beneficial.

Whitemoon Bristle
CRIT Rate is increased by 4~8%. After Normal Attacks deal Elemental DMG, the Foliar Incision effect will be obtained, increasing DMG dealt by Normal Attacks and Elemental Skills by 120~240% of Elemental Mastery. This effect will disappear after 28 DMG instances or 12s. You can obtain Foliar Incision once every 12s.
Alhaitham's signature weapon. Provides a small CRIT Rate buff and huge damage increase to his Normal Attacks and Elemental Skill based on his EM, and both of which are his primary source of damage.

Mistsplitter's Edge
Gain a 12~24% Elemental DMG Bonus for all elements and receive the might of the Mistsplitter's Emblem. At stack levels 1/2/3, Mistsplitter's Emblem provides a 8/16/28~16/32/56% Elemental DMG Bonus for the character's Elemental Type. The character will obtain 1 stack of Mistsplitter's Emblem in each of the following scenarios: Normal Attack deals Elemental DMG (stack lasts 5s), casting Elemental Burst (stack lasts 10s); Energy is less than 100% (stack disappears when Energy is full). Each stack's duration is calculated independently.
Provides a total of 40% Elemental DMG Bonus at R1 which applies to all of Alhaitham's Dendro attacks. Alhaitham can also easily meet the requirements to fully stack this effect all the time to utilize the buff.

Honed Flow
Obtain 12~24% All Elemental DMG Bonus. When other nearby party members use Elemental Skills, the character equipping this weapon will gain 1 Wavespike stack. Max 2 stacks. This effect can be triggered once every 0.3s. When the character equipping this weapon uses an Elemental Skill, all stacks of Wavespike will be consumed to gain Rippling Upheaval: each stack of Wavespike consumed will increase Normal Attack DMG by 20~40% for 8s.
Provides 12% All Elemental DMG Bonus, but the second part which gives 40% DMG Bonus only applies to Normal Attacks so his Skill and Burst won't benefit from it.

Protector's Virtue
HP increased by 20~40%. Additionally, provides an ATK Bonus based on 1.2~2.4% of the wielder's Max HP.

When an Elemental Burst hits an opponent, its CRIT Rate will be increased by 2~4%. Both of these effects last 10s separately, have 4 max stacks, and can be triggered once every 0.1s.
If you have BP, this is a great choice as it provides a lot of CRIT Rate plus Elemental Skill and Burst DMG Bonus.
