Overview

List of CUBs

Combat Unit Boosters are a feature that was added in the Echo Aria patch.

Combat Unit Boosters (also known as pets) are a type of equipment available to both Constructs and Transcendants.

Combat Unit Booster Overview

Combat Unit Boosters come in default class ratings of A-Rank and S-Rank. Combat Unit Boosters are primarily acquired through R&D, although A-Rank Combat Unit Boosters can also be crafted with materials obtained through Norman Restoration War.

Like most other equipment, they can be Overclocked to increase their stats and maximum level; this consumes Cogs and Support Overclock Kits. They can also be Evolved in much the same manner Constructs and Transcendants can, up to a maximum class rating of SSS+-Rank. Additionally, their skills can be enhanced by consuming Cogs and Support Skill Components. Combat Unit Booster Skill enhancement is randomized; upon expending 60 Components, the game will randomly choose one of the Unit's skills for level-up.

Combat Unit Boosters can be viewed and interacted with through the Combat Unit Booster interface, accessible in the Commandant's main office hub. They can then be equipped from the Members interface, next to the chosen character's weapon.

Combat Unit Booster Attacks and Skills

Combat Unit Boosters have one attack skill each, as well as several other passive skills. In combat, their attack skill must be charged before it can be used; this is done through the consumption of signal orbs by the equipped character at a rate of one charge per orb, with their attack skill becoming usable after six charges are accumulated.

At A-Rank, a Combat Unit Booster will be able to equip one attack skill and one passive skill of the player's choice. As it increases in Rank, additional slots for more passive skill equips will unlock, up to a maximum of five slots at SSS+.

By default, a Combat Unit Booster's main attack skill will inflict the same elemental damage used by the character that it is equipped by. However, its elemental passive enhancement will not change to match (for example, Yuan Ye, when equipped on Lucia: Dawn, will deal Lightning damage, but its passive enhancement to Fire damage will remain unaffected).

S-Rank Combat Unit Boosters have special, signature effects when equipped by specific characters (such as Frost Oath when equipped by Rosetta: Rigor).
