[b]TL;DR[/b] - Unbreakable is not returning full grenade energy anymore when you have a full meter, full grenade energy, and are running 100 Grenade stat. It also still doesn't work when you're in Transcendence on a Prismatic subclass. Unbreakable used to return full grenade energy when you had a full Unbreakable meter and the grenade energy was nearly full from taking continuous damage. Now it only returns ~75% - ~80% even when using 100 Grenade stat. On top of this, Unbreakable still can't be used when you're in your transcendence which is disappointing because that could open up a lot of fun avenues for harder content.
