Did a 100k will of the thousands strike using an Austringer, misfit, 21% and the full opulent scholar set. But when the nightfall ended I did not get the triumph for the high roller tribute dropping.
I got it done with all Opulence armour, Austringer, Beloved and Acrius (with catalyst, but that shouldnt matter). Got it done on 1st 100+k nightfall. However, the other one (the one that rewards the Drake tank statue) did not complete, and was at 60%. I had to complete another 100+k nightfall to get that.
