If you've been thinking about jumping back into the world of Diablo, today might not be a bad time with patch 2.3.0 rolling out worldwide.
It's one of Blizzard's massive patches, with a new wasteland to explore (the Ruins of Sescheron), a new artisan allowing players to catalogue their Legendary abilities, progression tracking for seasons and new Torment levels from 7 to 10 (with a minimum Paragon level of 100+).
There's a re-coding of skills so they can be bound to the left mouse button. Most of the heroes' skills have gotten another balance pass, with the Witch Doctor getting two or three pages of changes.
Bounties and nephalem rifts have been heavily tweaked. Low level crafting materials have been scrapped entirely. Magic and rare recipes don't drop any more and the cost of crafting has been streamlined across the board.
It's so large that Blizzard's preview video goes for almost six minutes. The introduction of Kanai's Cube is pretty important, and if you're a Diablo fan it's worth watching just for the cube's changes alone.
Patch 2.3.0 is live on the American servers and should be available across all regions by the end of the day. If you want to check out the finer details, head on over to the Diablo 3 Battle.net page.
