Developers' Notes: We want to reduce the maximum amount of time that [Surrender to Madness] can be maintained, without significantly impacting Shadow otherwise. Our intent in this hotfix is that it's still effective to use Surrender similarly to how it is currently used, but that its maximum potential in ideal situations is slightly less extreme.

• Hotfix (2016-09-26): Voidform stacks no longer increase while Dispersion is active.
  

Developers' Notes: We would prefer that [Surrender to Madness] not be as dominant as it is, and that it can't be extended for quite so long. However, addressing this further would require significant changes to the spec beyond what we want to do in a tuning pass at this time. We will look for an opportunity to take a more comprehensive look at this issue in a future patch.

• Patch 7.0.3 (2016-07-19): Added.
