## Hero Guide

Demon Cusack was released on November 15, 2022, through a regular Gacha banner. Demon Cusack is a demon support unit that increases attack-related stats and decreases the enemy's Crit chance and Crit damage. When a full ally demon team is present around Cusack, Cusack’s passive provides a 4% attack-related stats boost for each demon ally totaling to 16% increase. This is similar to Ominous Zeldris passive, but Demon Cusack also decreases the enemy’s Crit chance by 20% and Crit damage by 50%. Demon Cusack’s passive is better in most cases because it protects your allies from units like The Ultimate One Escanor, Light Mael, and Purgatory Meliodas. The units mentioned have outstanding Crit damage and high crit chance so Cusack lowering this means their damage output will be heavily crippled, giving your team the upper advantage in offensive and defensive categories.

### Pros

* Superior Demon support unit
* Cripples the opponent's Crit damage and Crit chance
* Does not need a high ultimate level to be useful
* Unique works in all modes

### Cons

* Demon Cusack is best utilized inside PVP content (including Hero’s Arena)
* Low attack power
* Restricted to Demon allies to utilize the second part of Cusack’s passive

## Gear Recommendation

The gear recommended for Demon Cusack is Health and Defense gear sets. Demon Cusack is widely used as a support unit for his passive so it will be best to increase his durability if you do choose to use Demon Cusack on the front line. This also applies when using Demon Cusack in the backline for a CC boost and support role.

Substats:

* Bracer/Ring - Attack
* Necklace/Earring -Defense
* Belt / Rune - HP

## PVP

The optimal team composition for Demon Cusack is a standard full demon team setup. The best units included in this setup are Festival Estarossa, Purgatory Meliodas, and Dark Demon King. Demon Cusack provides good support to this team, giving frontline units 16% extra damage and allowing Meliodas, Estarossa, and Demon King to melt enemies while all at the same time Demon Cusack is providing Crit Defenses as well. He can pair Demon Cusack and Nebula Zeldris together for a big basic stats increase.

Another good team to mention if you decide to use Demon Cusack on the offensive is to combine him with Blue Lillia and Green Demon Chandler. Lillia will increase Cusack’s Pierce rate by 50% and Chandler will increase it by an additional 40%, further increasing Cusack’s Pierce card damage output. This team is something to experiment with for fun and with friends not really something you will take inside high PVP.

Overall, Demon Cusack is an excellent pickup and very beneficial for the Demon team. Demon Cusack can replace other backline units like seasonal Nebula Zeldris or Ragnarok Ban. Cusack does not take much investment. Just equip him with high CC gear, place him on the team, and let his passive go into effect.

## Story

Cusack is one of the highest-ranked demon of the Demon Clan as well as Zeldris' former master. He and Chandler were once a single entity known as the "Original Demon".

The "Original Demon" was created by the Demon King as his most trusted retainer. Acknowledging his own immense power, the demon rebelled against the Demon King only to be dealt with and punished. For rebelling against the Demon King, the "Original Demon" had it's body and soul split in two, and was tasked with the duty of being instructors to the two demon princes to become candidates for the throne of the Demon King.

Like Chandler's attachment to Meliodas, Cusack is very much attached to his student, Zeldris, expressing the utmost confidence and loyalty to the Demon King's second son. This extends to the point that he believes Zeldris to be worthy of reigning the Demon Clan next instead of Meliodas. This attachment led him to express complete anguish and shame along with rage when he ranted about how he failed to protect Zeldris when Meliodas pinned him down upon his arrival to Camelot.
