It's only been a few days with No Rest for the Wicked and Moon Studios has already released two patches to address the balancing and performance issues that players have been experiencing post-launch.
No Rest for the Bad Guys – First Major Update
Hotfix One landed yesterday and addressed a number of these balancing issues, including a reduction in repair costs, stamina costs, fall damage, and a boost to the drop rate on a number of resources that many players have been needing more of in their playthroughs. Today’s Hotfix Two focused on performance and bug fixes, according to devs over on the No Rest for the Wicked blog.
Many players playing No Rest for the Wicked have been experiencing serious performance issues, so hopefully today's hotfix addresses many of those issues. Also planned for Hotfix Two is increased Durability for all tools, a few loot adjustments (specifically related to the Water Channel key), and some combat improvements surrounding the Wolf, Plague Wolf, and Riven Twins Bosses.
Here are the full patch notes for No Rest for the Wicked's Hotfix Two.
