Here's the Delves PC changes for today.

Patch Notes:
  • Challenge Delves will now only spawn a Shadowy Soul Vault on specified depths after the completion of at least 3 consecutive depths rather than always spawning a Shadowy Soul Vault at specified depths.
  • Fixed an issue that could result in the Cursed Skull Pile in Delves allowing bosses to be resummoned for no additional rewards.
