Alhaitham Guide and Best Builds for Genshin Impact

Strengths

• Fantastic On-field DPS
• Great Dendro Spread
• Amazing elemental trigger

Weaknesses

• Needs a strong team to bring out his potential
• Needs elemental reactions for damage

Alhaitham's primary method of damage is his Dendro abilities, which are based upon stacking Mirrors ( Chisel-Light Mirror). These Mirrors convert his damage to Dendro and are generated a multitude of ways; these are as follows:

• His first Ascension skill, the Four-Causal Correction passive (Charged Attack produces a Mirror);
• His Universality: An Elaboration on Form talent;
• His Particular Field: Fetters of Phenomena talent.

These will all produce Mirrors for him to amplify his damage. The build gets fun when using all these mirrors for a rapid application of Dendro. Combined with Hydro, this creates Dendro cores and then you can trigger them with other elements like bombs. However, be aware that Alhaitham's Energy Recharge requirement will need to be as high as 200% for solo Dendro teams and around 150% for duo/triple Dendro teams.

Light of Foliar Incision is the obvious choice for a 5-star weapon for Alhaitham, not only because of its CRIT DMG increase, but also because we gain several other increases from normal attacks: CRIT Rate, Elemental Skill damage, and Normal Attack damage. This effect holds for 28 instances or 12 seconds overall. While the attack buff only lasts for 12 seconds with no way to increase its duration, it does not have a cooldown, which means it can essentially always be active.

The 4-star option, Wolf-Fang, offers an alternative CRIT stat choice, focusing on CRIT Rate instead of CRIT DMG. The weapon's skill itself offers a flat boost to Elemental Skill and Burst Damage. It also stacks CRIT Rate for both skills, up to 4 stacks total. This weapon can also be crafted and can easily be refined to its top rank.

Lastly, a note about Alhaitham's artifacts — most of his equipment offers boost to his Dendro Damage and Elemental Mastery. These can be split into groups of 2 or full sets, but you are mainly looking for the combination with the best sub stats. Alhaitham does need a strong amount of Energy Recharge (target above 150% minimum) so you can keep his rotations quick. Typically, his Energy Recharge requirement will also heavily depend on his team composition, with some characters acting as a battery for him to generate energy particles from.

Alhaitham requires time on the field to generate Mirrors, which will be key to his Dendro application for the generation of Dendro cores — essentially bombs for your team. He can be played in several different ways; from short burst combos with a high Energy Recharge requirement to a longer combo rotation focusing on maximizing your mirror count and uptime. Which of these two methods you choose will highly depend on your teammates and how much time you need to rotate all their skills onto the field. Remember, Alhaitham has the advantage of being extremely flexible in his gameplay, so he can split up his field time quite easily, focusing on getting the best results out of his teammates.

As for you team, Alhaitham's DPS should always be your top priority for keeping him buffed and constantly dishing out damage with his Dendro attacks. He typically plays with Hyperbloom or Quickbloom teams to cause elemental chaos against your enemies. These units should also focus on strong Elemental Mastery builds to add to your teams overall DPS. This playstyle is very fast, and with well-timed rotations — using all your characters skills — you will see some truly powerful elemental reactions.

Alhaitham is an on-field DPS with excellent attack power and mediocre survivability. With that in mind, we will be targeting off-fielders and support characters that can offer Elemental Reactions for his Dendro abilities to trigger, Damage buffers to keep Alhaitham's DPS high, and finally healers or shielders to keep him on the field when taking any damage.

For this Quickbloom team, Alhaitham is our main driver for Elemental reactions, fighting on-field the majority of time using his mirrors. Furina and Baizhu will combine their elemental abilities to produce Dendro cores all around the battlefield. To create the Hyperbloom reaction, Kuki Shinobu has an excellent kit to use or you can use Raiden Shogun for a large Electro burst to trigger the Dendro cores. Once this triple combination is out on the battlefield, Alhaitham can use his elemental abilities to help keep the reactions going, as he fights against the enemies.

This Aggravate build depends on leaving Electro effects on the field, while using Alhaitham's dendro attacks to trigger multiple instances of Aggravate. The fun element of this build then uses Kaedehara Kazuha to pull enemies into groups with his Chihayaburu and his Kazuha Slash to combine elements for a huge boost in damage. This team does function without a healer so we use Beidou's Stormbreaker for the damage reduction boost to keep us in the fight while using food if necessary. Rotations for this build are very forgiving and the main idea is to simply keep some Electro elements damaging enemies on the field while using Alhaitham.

This team has a lot of flexible slots to play around with. The setup does work best with a high HP Zhongli build for shields so you can ignore the majority of the enemies damage. We will have a ton of Dendro application on field between our Dendro flex slot and Alhaitham, as for our Electro component in the build, this will depend on your preferred playstyle.
