Team Building

Tanks and damage dealers receive the biggest bonus from mutation and traits. If those roles are left basic with no mutation or trait, the score drops sharply and can fall to an F-tier build. To improve your rating, prioritize mutations and traits on the front line, use a strong healer/revive support pick when possible, and level up the units you rely on most. Kiwusuke is especially flexible because he can cover the healer or revive support role.

Team guidance

You are missing a tank. Add a durable front-line unit such as Itadoro or Bon to improve your team's stability.
