They're simply versions of poe currency present support gems. By way of example, Awakened Ancestral Phone targets three opponents, while Ancestral Call only aims two. This is a massive buff, and with so many this will allow especially ones who can utilize Awakened Support Stone that are new, assembles. It will be quite interesting to see how precious they are, and how costly it is going to be to find level versions, if they exist.
When it may be overshadowed by the rest of the changes, there is also a challenge league launch well. You will see samples that you kill. These samples will be used to summon a supervisor. Rewards will be dropped by this boss, and potentially grant bonuses, dependent on how powerful the substances used to create him was. These directors will also drop a new type of money, called Catalyst, which may increase the standard of audio, Amulets, and Belts (all items that previously had no quality rating).

It'll reach a stage where things will probably kill you in one hit. This build by taking another approach of accepting that everything will kill it in one 20, avoids that. If this build is ever hit, it expires. This makes thickness 300 more dangerous, but allows you to handle 4000! This is the construct used by all of the deepest delvers as of writing this, at Blight League, at least 2 of whom have passed depth 5000.
