From GRAY RAVENS
Constructs are designed for the majority of the game's content and possess default class ratings of B-Rank, A-Rank, and S-Rank.
Constructs have three predesignated classes: Attacker (dealing damage), Tank (weakening enemies), and Support (healing and buffing allies). They cannot be deployed in the same team as Compositers.
With the exception of B-Rank characters, Constructs are predominantly acquired through R&D.
- B-Rank Constructs are given automatically via story progression.
- A-Rank Constructs are guaranteed every 10 pulls.
- S-Rank Constructs are guaranteed at a minimum of 60 pulls.
