Temporarily reduce damage taken and how easily you are interrupted.Description
Steelskin is Barret's default ability in Final Fantasy VII Remake. It provides Barret with an unique buff that increases both his Defense and Magic Defense, as well making him less susceptible to being interrupted while attacking.
Steelskin reduces all damage Barret takes by 30%. It is one of Barret's abilities that, alongside Lifesaver, serves him in the role as a "tank" type of character, allowing him to protect the party. Steelskin's buff is is unique in that it cannot be dispelled by enemies, and it stacks multiplicatively with other buffs such as Barrier and Manaward. This turns Barret into a very resilient character capable of taking a lot of punishment.
Steelskin can be used in conjunction with Lifesaver or Provoke Materia to draw fire away from enemies, and then resist damage he takes. Barret will not reduce damage projected onto him by Lifesaver, but he will reduce damage he receives himself. Other buffs and Complete Materia can further improve Barret's ability as a tank, allowing him to sustain a lot of damage.
