The Robe of the Sage is incredibly resistant to physical attacks and can be summoned and de-summoned whenever. You can switch to attack mode which trades the suits defense for overwhelming attack power. The suit can be designed to whatever you desire. It is also sentient to the point where it can protect you from dangers you aren’t aware of. At no point can this robe be permanently destroyed, reforming itself in time no matter its condition.
