Recently, GGG announced the Development Manifesto regarding the integration of the Abyss content in Path of Exile because many of players are interested to know the future of the Abyss mechanics. A lot of effort went into making Abyss. And we also strive to bring inexpensive poe orbs to our players.
GGG made new monsters specifically for Abyss. They also pushed the rewards as far as their felt they could. Abyss Jewels were comparable to other Jewels on the passive tree and opened up new build possibilities. The Stygian Vise belt base type and uniques which let you place the Jewels in your gear made them even more powerful.
The content will extend into Maps. In the league, Abyssal Depths happened around level 40, so they are basically pushing the league content (and also the Depths) further into the game.
Abysses will occur 10% of the time in instances, with some adjustments for smaller and special areas. The 10% will also apply in maps. As Breaches will occur 10% of the time in maps, players have a considerable chance of finding either a Breach or Abyss in their map.
GGG have increased the odds of a Lich occuring in the Depths, so there is a still a reasonable chance of finding them, despite Abysses being much less common than they were in the league.
Abyssal Depths and Troves will also be able to drop maps, so the content will never be penalising to play.
Abyss Jewels and Stygian Vises make up much of the reward for the league. Abysses will still have good general drops from their Troves, and Depths will continue to be rewarding. However we will reduce the shower of Jewels from each Abyss. An Abyss will have a magic Jewel, and some chance of a rare Jewel.
Belts will now only come from Depths and Liches. There will always be a Stygian Vise drop from a Stygian Spire or a Lich.
As these bases are now only available from this side content, there is now no chance of a Stygian Vise also being an Elder or poe items of Shaper. While this combination does occur in the League, this will not be the case once the content is in the core game.
