Is really ****ing good! Prismatic or void. And it doesn't scale with your grenade stat, but it does scale with deltas. So seemingly, the harder the content the better it is. Here's the main selling point: 95% DR You can run and jump with it. You can body block enemies while your team safely DPS's. I'll give one anecdotal cadence: I'm grinding Onslaught right now... For the intermediary, I can grab the spark... and run it effortlessly. No big whoop... seriously, that's nothing... amplify, invis, yada yada... not a real achievement but still cool. Bosses. I'll pop unbreakable body block the boss, charge fully... blast, pop prismatic... nade, throw axes... Boss is at 20/30%. It's a good combo. I can solo the Tormentor and all the major HVTs in less than 5 secs with that combo. Unbreakable is an S tier Titan Aspect... and I don't see enough people using it. For DR... panic survivability alone, grabbing rezs. The "body block" is a disorient effect that messes with enemy scripts when you hug them with it. And you get 3 fragment slots.
