Best Choice for Nothin’ But a Hound Dog

Choose Lupa's Brain for Better Survivability

Choice Benefit
Rey's brain Increased attack damage
Violetta's brain Increased movement speed
Lupa's brain Increased toughness

Benefits from each brain only apply to Rex and not to your character.

We recommend choosing Lupa's brain as this increases Rex's toughness, effectively allowing him to be more durable in battle. This allows you to focus on taking down enemies without having to worry much about Rex's wellbeing.

Do note that you can choose any of the other brains should it benefit your playstyle or build.
