BlizzCon — Diablo 4 Campfire Chat No Nerfs Planned For Season 2
Developer’s Note: Players communicated that reworking all or most of their Paragon Points was a common occurrence. We've added this button to make it easier to do big respecs, along with the increases to Gold income from Whispers in Season of Blood.
Players can test their mettle against a new inanimate and un-killable foe—the Training Dummy! The dummy is located in an underground room, the entrance can be found in Kyovashad. The training room contains a stash and the Training Dummy. Players can choose between attacking one Training Dummy or a small group of them, and dictate whether each Training Dummy is of Normal, Elite, or Boss monster difficulty.
