The Wither regenerates health after it reaches half-health and drills a hole in the ground until its boss bar unloads from the screen.

The Wither, which doesn't naturally regenerate health on this edition, for some reason can regenerate health with the following steps. To make matters worse, it also retains its second phase behavior, potentially making it harder for players to defeat the regenerated Wither.

Steps to Reproduce:

  • Spawn the Wither.

  • Damage it until it reaches half-health.

  • Repeat the previous steps as necessary until the Wither drills a hole in the ground deep enough for its boss bar to unload.

  • Move back toward the Wither to reload its boss bar.

Expected Result:

The Wither retains its health as it was before its boss bar got unloaded.

Actual Result:

The Wither regenerates health. The more time its boss bar lasts unloaded, the more health the Wither regenerates.

We can only track one issue per report. I have removed the information about the other wither bug you described from this report.

For some reason, the first attachment is no longer working. Here's a reupload of the said attachment.

I cannot reproduce this. I damaged a wither to a bit less than 1/2 health, moved 250 blocks away, and waited for over 15 minutes. When I went back it had the same amount of health.

The videos attached do not clearly show the wither being unloaded. It looks like it is within simulation distance the entire time. That said, I also cannot get a wither to regenerate at all in a test world on hard difficulty. I am not sure what the conditions are.

I'm going to try to look further into this. I’ll let you know what I find out, or at least what I think I find out.

So, I think I found something out. This bug seems to happen more frequently when the Wither, upon reaching half-health, drills a hole in the ground until its boss bar disappears. I found out that the player doesn't necessarily have to move away for this bug to be triggered, just like it's shown in the videos attached. Although I'm still not sure if this is the only trigger, or it simply happens more frequently with this.

Thank you for your report!  

However, this issue has been temporarily closed as Awaiting Response  

Could you please provide more details and media files. As we have no repro of this issue. 

  • If you are using addons could you please list them all? 

  • As mentioned below, do you know if this issue happens frequently or just once? 

  • Does the issue also occur in creative mode?

  • Do you have more steps or tips to help recreate this issue?

  • No, I'm not using any addons.

  • It can happen every time the Wither drills a hole in the ground until its boss bar unloads from the screen.

  • Yes, it can also occur in creative mode.

  • The steps and tips I mentioned in the report is all I've got for now.

After performing a few more testings, I can now confirm that this bug is very likely only triggered by the Wither drilling a hole in the ground until its boss bar unloads from the screen. At this point, it's highly unlikely it's triggered by something more specific. The first attachment on this comment shows what I initially thought could trigger the bug, while the second and third attachments show what actually does trigger the bug.

The report has been edited to fit my findings.
