After a wave of complaints from select parts of the Elden Ring community, FromSoftware appears to have caved to the demands to lower the difficulty of the game's Shadow of the Erdtree DLC. Following a calibration update that is applied once you log into the title's multiplayer server (look for version 1.12.2), the Shadow Realm Blessings that improve your attack power, damage negation, and Spirit Summons will have even more of an impact.
The change list on the Bandai Namco website explains upgrades sourced from Scadutree Fragments and Revered Spirit Ash have been increased "for the first half of the maximum amount of Blessing enhancements", while the "second half" will be "more gradual". This means you'll feel their effects more in the earlier stages of the DLC, giving you a better chance against the first set of Boss Fights. In addition, the last level of each upgrade has been "slightly increased".
To feel the benefits of these character enhancements, you'd still need to actually find and collect the Scadutree Fragments and Revered Spirit Ash spread throughout the new map. Despite the new mechanic being pointed out and explained in-game, some hardcore players have avoided the benefits they bring. This has brought about a wave of complaints and even some review bombing, with suggestions the expansion is simply too difficult.
