For those of you that do not know how the Unbreakable aspect works, when you take damage, you fill up a bar that will release a “frontal blast” when letting go of the grenade button or after your grenade energy depletes. The more you fill up the bar, the more damage the “frontal blast” does. When using Ursa or Spirit of the Bear, blocking with Unbreakable grants you super energy. However, the super energy you are granted from blocking damage stops after the aforementioned bar fills up. With that being said, I believe the total amount of super energy you can receive is about half of a single bar of our total super bar. Just some information for fellow Defender Titans that had their interest peaked when you saw the Unbreakable aspect and the Ursa buff.
