That's why I really want something like this. You don't even have to be very informative. The waves tell the history of the battles. As long as Bungie doesn't get really lazy the story telling potential without saying much like they seem to love is there. Since its for destiny 2 most likely or much later you could even make it very difficult and award gjallahorn for completing it randomly like the grimoire says. Same stats as RNG one but maybe a slightly different skin to show you completed the waves Not sure how Kabr would work too much except knowing him corrupted by the vex armor he made Being the last wave.
