We’ve just deployed the following additional adjustments to the Beta:

Tyrannical affix

• Health bonus on bosses reduced to 25% (was 30%).

Dungeons

• Reduced all enemy damage dealt by 7% on all Mythic and Mythic+ difficulties.

We’ve recently deployed a hotfix to the Xal’atath’s Guile affix that addresses its damage not scaling with keystone levels. We will continue to monitor the impact of Xal’atath’s Guile on Beta testers running keys 12 and above and make adjustments if necessary.

For further context, this change was focused on making the 2–11 keystone experience better.
