Universality: An Elaboration on Form

Rushes forward, dealing Dendro DMG to nearby opponents when the rush ends, causing a Chisel-Light Mirror to form.

Holding this skill will cause it to behave differently.

Hold

Enters Aiming Mode to adjust the direction of Alhaitham's rush attack.

Chisel-Light Mirror

When this skill is unleashed, Alhaitham will generate 1 Chisel-Light Mirror. If there are no Mirrors at this time, he will generate 1 additional Mirror. Chisel-Light Mirrors will have the following properties:

·When he possesses Chisel-Light Mirrors, Alhaitham's Normal, Charged, and Plunging Attacks will be converted to Dendro DMG. This cannot be overridden.

·When attacks of the aforementioned kind hit opponents, the Chisel-Light Mirrors will unleash a Projection Attack that deals AoE Dendro DMG based on the number of Mirrors on the field.

·A total of 3 Chisel-Light Mirrors can exist at once.

·The Chisel-Light Mirrors will disappear one after the other over time, and will all disappear when Alhaitham leaves the field.

"Truth inherently exists amidst uncertainty. Even the greatest of scholars are not immune to error."

The DMG of both aforementioned abilities can be increased by a maximum of 100% this way.

Law of Reductive Overdetermination

When Alhaitham crafts Weapon Ascension Materials, he has a 10% chance to receive double the product.

Constellations

The six nodes unlocked with the character's Stella Fortuna.

  1. Intuition

    When a Projection Attack hits an opponent, Universality: An Elaboration on Form's CD is decreased by 1.2s. This effect can be triggered once every 1s.

  2. Debate

    When Alhaitham generates a Chisel-Light Mirror, his Elemental Mastery will be increased by 50 for 8 seconds, max 4 stacks. Each stack's duration is counted independently. This effect can be triggered even when the maximum number of Chisel-Light Mirrors has been reached.

  3. Negation

    Increases the Level of Universality: An Elaboration on Form by 3.

    Maximum upgrade level is 15.

  4. Elucidation

    When Particular Field: Fetters of Phenomena is unleashed, the following effects will become active based on the number of Chisel-Light Mirrors consumed and created this time around:

    ·Each Mirror consumed will increase the Elemental Mastery of all other nearby party members by 30 for 15s.

    ·Each Mirror generated will grant Alhaitham a 10% Dendro DMG Bonus for 15s.

    The pre-existing duration of the aforementioned effects will be cleared if you use Particular Field: Fetters of Phenomena again while they are in effect.

  5. Sagacity

    Increases the Level of Particular Field: Fetters of Phenomena by 3.

    Maximum upgrade level is 15.

  6. Structuration

    Alhaitham gains the following effects:

    · 2 seconds after Particular Field: Fetters of Phenomena is unleashed, he will generate 3 Chisel-Light Mirrors regardless of the number of mirrors consumed.

    · If Alhaitham generates Chisel-Light Mirrors when their numbers have already maxed out, his CRIT Rate and CRIT DMG will increase by 10% and 70% respectively for 6s. If this effect is triggered again during its initial duration, the duration remaining will be increased by 6s.
