Skill Summaries are used to upgrade the Operator's skills, including Mastery training.
CA (Aerial Threat) daily operations are the best place to farm Skill Summaries.
Chips are used to promote Operators. Each class have their own distinct Chips which are divided into three types:
- Standard Chips, used to promote all Operators (except 3★ ones) to Elite 1. They are awarded for completing the first of the Chip operations.
- Chip Packs, used to promote 4★ Operators to Elite 2 and produce Dualchips (see below). They are awarded for completing the second of the Chip operations.
- Dualchips, used to promote 5★ and 6★ Operators to Elite 2. They can only be produced at Factories, requiring two of the respective class' Chip Pack and one Chip Catalyst.
Chip Catalysts can be purchased in the Shop Vouchers Store.
Class Tokens can be used to improve the potential of Operators of the respective class, but each level requires four of the corresponding Class Tokens.
