from a steam review:

After countless teasers and 3 years of waiting, it is out! New story, new game mode, new mastery, and FINALLY affix transmutation (F to those who’ve spent hundreds of hours grinding ideal double-rare items for their builds), plus dozens of QoL updates and improvements. Perfect time to come back to my favorite ARPG to scream again
