is there a FAQ that covers most of the new stuff? I saw the forum FAQ but it mostly covered the gameplay changes.
for example, i have no idea what all the Transmutation Embers i have do. I didn't see that anywhere.
There is no in-depth info post about what you should/could do at lvl 100, there is an info post somewhere if im not mistaken, but its not all that in-depth about it.
But a fast goto would be:
Derinkuyu (t0 raid, first raid): You want to farm the trash mobs in Derinkuyu for Damage Reduction and Health skulls so you can survive the boss encounters
Or'ak Pass/Basin (T0.5 "raid", second raid): Drops Legendary Skulls and T0.5 stuff ofc.
Darkness Falls(T1/T1.5 raid): Currently the hardest content in Synergies, has great items and great Mythical Skulls to farm, has a zone Debuff you have to overcome.
