Ritual Sites
Ascendant Voidcore Drops
Players have found out that the Ascendant Voidshards that are needed to craft Ascendant Voidcore for Weapon and Trinket upgrades drop randomly from various end-game content and also don't appear to be time-gated. This includes:
Nightmare Prey
Bountiful Delves
Ritual Sites
Raids
Dungeons
It's unclear at this time if different sources have different drop rates. Raids seem to have around a 33% drop rate from initial tests and Ritual Sites have a lower drop rate, but this is far from confirmed.
Best Farm for Ascendant Voidcores
The best farm for Ascendant Voidcores at the moment seems to be Tier 1 Ritual Sites, as these have a chance of dropping Ascendant Voidshard even on tier 1. While this can be done solo, the fastest way to do this while on the Zul'Aman Ritual Site is to do this in with more players. You can duo with one party member going down the stairs to the left 3 objectives at the start, and one party member going right at the start to the right 3 objectives. You can also do this in a group of 5 players with each person picking one LT which is also very quick.
This allows you to clear the Ritual Site in about 2 minutes, which should be the fastest activity completion of the things that drop the fragments. Even if the drop rate of these is lower, Ritual Sites are infinitely farmable and are very quick to finish and can be done with small group sizes.
