What achievements changed with the release of 3.0?

The release of the 3.0 Fall of Oriath expansion removed difficulty levels and achievements previously related to beating the game in higher difficulties got changed into different achievements.

Which achievements turned into which new achievements?

I know I now have Deicide (kill a god and obtain their power), and apparently achieved it in december 2016, but I most certainly did not do that yet, and most certainly not back in December, half a year before the expansion was even released...

Other achievements that I got that were most certainly changed:

• Deadly Sins
• Omnipotent
• Loyal to the End

There might be others I have, but it's been a long time so I don't remember exactly what happened where in the story.

Solution 1:

These are the ones that changed and are listed in the official patch notes. These changes are visible through the in-game achievements menu.

The Achievements Breaking Free, Ascension, Vengeance have been renamed to Challenger, Leader and Lord, and are no longer gained by completing the story on various difficulties. Instead, these achievements are obtained by completing the first three Labyrinths.

The Achievements Fearless, Dauntless and Indomitable are no longer gained by completing the story on various difficulties in Hardcore. Instead, these achievements are obtained by completing the first three Labyrinths on Hardcore.

The Achievement End of the Nightmare no longer requires that you kill Malachai, the Nightmare with each class, and instead just require that you kill Malachai, the Nightmare once.

Also as you have noticed, the timestamps for some achievements on the Steam client may be wrong. This is because if you had an old achievement that was renamed after the 3.0 release, it kept the old icon and achievement date stamp, but has the new name and description.

After looking through my achievements and comparing to the wiki page, I found some examples. In your case for instance "Deicide" on Steam has the same icon as "Bringer of Pain" from the wiki which used to be the achievement for killing Maligaro.

Note that the following only applies to the achievements listed in the Steam client. The achievements you see through the in-game menu include both the old and new achievements

These are the achievements I found that were not only renamed but had their description/methods of unlock changed:

Gladiator: Fully clear the Colosseum end-game map. -> Emperor: Complete the Endgame Labyrinth in a Standard League.

Cleanser: Fully clear The Harvest. -> Untouchable: Complete the Endgame Labyrinth in a Hardcore League.

Purifier: Kill Voll, Emperor of Purity. -> Heretic: Kill High Templar Dominus.

Umbra Slayer: Kill Shavronne of Umbra. -> Loyal to the End: Kill Argus.

Dispelling the Curse: Kill Doedre Darktongue. -> Treasure Hunter: Kill Izaro and have him drop 3 treasure keys.

Bringer of Pain: Kill Maligaro, The Inquisitor. -> Deicide: Kill a god and obtain their power.
