Heizou Hangout Event

Heizou is a 4-star character from Inazuma that uses a catalyst in battle. He first appears in his hangout event where you investigate his disappearance. Heizou currently serves as a detective for the Tenryou Commission.

Heizou is best described as witty and free-spirited. Despite working for the Tenryou Commision, he often takes on cases based on his own personal beliefs. This gets on the nerves of his boss Kojou Sara, but she often lets it slides due to the results he brings in. Heizou’s detective skills are top-notch due to his increased sense of logic and reasoning. His skills have made him sought after for any cases that are difficult to solve.

Heizou used to work with Bantan Sango in their own detective agency called Bantan Sango & Heizou Detective Agency. However, he left due to conflicts in their respective visions of what being a detective was. Heizou believes a detective should find more than the truth, and work to deter crime from happening. Detectives can’t stop the crimes from happening, but he hopes to change that one day.

Shikanoin Heizou Skill Talents

As the first male catalyst user, Heizou excels as a DPS or sub-DPS with his ability to deal Anemo DMG and Swirl with other elements. His elemental skill allows him to deal massive Anemo DMG to the enemy when all 4 stacks of his Declension are collected.

Heizou’s normal attack

Heizou’s normal attack, Fudou Style Martial Arts, performs up to 5 Anemo punches. His 1st hit will strike the weakest, with his 5th hitting the hardest. Heizou’s 4th attack hits 3x on the enemy. His charged attack consumes stamina to unleash an Anemo kick. As a main DPS, Heizou can unleash rapid fast Anemo attacks on the enemy, triggering Swirl if he reacts with another element.

Heizou’s charged elemental skill

His elemental skill, Heartstopper Strike, has both a press and hold effect. The press effect will deal a swift punch to the enemy. Holding down the skill button, allows Heizou to charge up his skill and gain Declension stacks. He can have a total of 4 stacks, increasing the power of his elemental skill with each Declension stack. When Heizou has all 4 stacks of Declension, he will gain the Conviction effect, allowing his next elemental skill attack to be stronger and have a wider AoE. His elemental skill will automatically be released once he is at full stacks. Stacks of Declension will remain if Heizou switches out and can be seen by the circle next to him on the field. The Delension stacks have a duration of 60 seconds, with his skill having a cooldown of 10 seconds. The scaling of Heizou’s elemental skill is great to deal massive Anemo DMG to the enemy, especially with his Conviction effect active. This is the optimal talent to upgrade for Heizou for his damage output.

Heizou burst

Heizou’s elemental burst, Windmuster Kick, allows him to leap into the air and use the Fudou Style Vacuum Slugger to kick Anemo DMG toward the enemy. The Vacuum will explode when it hits the enemy and create an Arresting Tunnel to pull in nearby enemies and objects. If the Vacuum hits an enemy affected by Pyro, Hydro, Cryo, or Electro, it will create a Windmuster Iris. This Windmuster Iris will deal elemental damage to the enemy based on the element they were affected with. This effect can affect up to 4 enemies hit by his elemental burst. However, one enemy can not be affected by Iris of multiple elements. Heizou’s burst can deal elemental damage to the enemy and also act as crowd control to pull them closer. It also has a low energy cost of 40 and a 12 second cooldown.

In co-op, Heizou can act as a DPS that can deal Anemo DMG and Swirl with other elements. His ascension talent also allows him to support the team with an Elemental Mastery buff.

This talent will allow him to easily gain stacks of Declension when his Anemo attack meets another element besides Geo.

Ascension 4 talent, Penetrative Reasoning, provides a supportive buff in elemental mastery to his teammates when his elemental skill hits an enemy. The bonus does not apply to Heizou himself. This talent is great for increasing the reaction damage of the party and also helps increase the overall damage of characters that scale with Elemental Mastery like Sucrose or Kazuha.

Heizou’s recommended artifact set is the Viridescent Venerer to increase his Anemo DMG and decrease enemy elemental resistance while powering up his Swirl DMG. This is the best artifact for any Anemo character. You can also use a 4-piece Noblesse Oblige for a more support build or sub DPS.
