Diablo III's Season 21 content is now live for all regions and platforms, bringing with it new class sets, item and skill changes, and season journey rewards. You'll be able to get cosmetic rewards previously available from Season 9 as part of the content update, but there are a couple of new additions, as well.

Season 21's theme is Trials of Tempests, and during the season your character will occasionally channel an elemental power that you can utilize for a short time. You can crush enemies with snowballs, breathe lightning, rain meteors, conjure a flame wall, or even cast tornadoes.

Those who complete the season's journey in the Trial of Tempests will get the Stupendous Contraption pet and the Industrial Portrait frame. This is in addition to the Season 9 items that are also available for completing it.
