Talents and Constellations
For skill and talents, we are covering Alhaitham combat talents, passive talents, and 6 level of constellations.

| Sword of Hetuvidya (Normal Attack) | – Normal Attack: Performs up to 5 rapid strikes. – Charged Attack: Consumes a certain amount of Stamina to unleash 2 rapid sword strikes. – Plunging Attack: Plunges from mid-air to strike the ground below, damaging opponents along the path and dealing AoE DMG upon impact. |
| Universality: An Elaboration on Form (Elemental Skill) | 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. |
| Particular Field: Fetters of Phenomena (Elemental Burst) | Creates a Particular Binding Field and deals multiple instances of AoE Dendro DMG. If Chisel-Light Mirrors exist when this ability is unleashed, all such Mirrors will be consumed and increase the number of damage instances dealt. 2s after this ability is unleashed, new Chisel-Light Mirrors are generated for Alhaitham based on the number of Mirrors consumed: – If no Mirrors were consumed, 3 will be generated. – If 1 Mirror was consumed, 2 will be generated. – If 2 Mirrors were consumed, 1 will be generated. – If 3 Mirrors were consumed, none will be generated. |
