Hey all, just got to tier 3 and now I have to go find aspects for my build. What are the best ways to farm for them? Should I just do the dungeons on the maps over and over or are there better options?
If you're at tier 3 start doing helltide and nightmare dungeons for better loot. You can of course do the normal dungeons for your base aspects that go into your codex of power. Sometimes it's nice to have a base version of an aspect just as a backup so your build won't completely break if you swap out an item, even if that base version gives you lower stats compared to the ones you get randomly on loot.
Also, do events that give you obols, which you can trade at the curiosity vendor.
Should I be trading obols for gear or the whispering keys? So far I have been rolling the gear but no clue if it is more efficient to target the chests
Whispering keys are just for the random locked chests you find when exploring the world. I've generally found them to be okay-ish. I just keep 2 whispering keys on me at all times just in case. You run into those chests rarely though, so it is best to just buy the gear with the obols.
Also keep in mind that your main goal is to get to tier 4 as soon as possible by beating the capstone dungeon, I wouldn't worry too much about being a completionist about the side quests at tier 3. Best to save a few for Tier 4 anyways for the extra experience.
Helltides are currently the most efficient way of farming legendaries. There are 2 mystery chests per helltide, 1 per region. Each chest usually drops 3-5 legendaries and costs 175 cinders. The chests reset on the hour, so if the helltide starts at the right time and you can farm cinders fast enough, it's possible to get 4 mystery chests per helltide. (6 if the helltide is in Hawezar since that one has 3 regions). During helltide, public events are the best way to farm cinders.
Now, I would suggest playing the game normally during helltide the first few times for the most fun. but if you really just want to cut out all of the unknown, use helltides.com for the chest locations and timers.
