I just ran a group run in undercity with the Tribute of Ascendance (Resolute) from the Christmas event. We had tier 4 rewards, but every single one of us only got non-ancestral normal legendaries. There were no unique drops of any kind for any of the 3 players, much less ancestral. We completed the run on Torment II.
i’ve seen many reports now of undercity sometimes just not dropping any of what the tribute should make it drop, maybe that’s still a thing
just to be clear though, the tribute does nothing to increase drop chance of ancestrals, and also the uniques would only drop for the player that used it (resolute, not united)
if it’s not still that same issue mentioned above, however, i wouldn’t be surprised if this particular tribute is just broken as somehow everything with this event seems to be lol
This has been a well-known bug ever since VoH release - can happen with any tribute.
Reports flood in everyday but they don’t look on the forums or refuse to fix
I used this tribute 6 times, and got nothing 
I have run both Tribute of Ascendence Resolute and United. On the United run, I got 2 mythics out of 3 runs(my party member got only 1 sadly). Out of 6 Resolute runs, I got 4 mythics, 2 in one run, 2 in another. I should mention that all of these runs were done in T2. I am working my wy up to trying them in T3, but imo, 4 drops out of 6 tries is not bad. I ran these last month, middle to end of the month. The thing i am having trouble with is the runes to craft mythics with. After looking up which ones are needed, some them have never dropped for me(like Met, Yom, and Ner). Is there a way to farm specific runes?
No, right now it’s random craft or drop
