Hi! With the weekly patch on the 16th of May this was in the patch notes: The following has changed for the skill Shake Off. Invincible effect has changed to Super Armor effect. Moving distance has increased when skill level goes up even in Iron Buster mode. However with the emergency patch on the 17th of May, this change is now reverted or missing, and behaves how it previously did. There is no mention of it in the patch notes for the 17th. Is this an intended change and missing from the notes or a bug? Edit: This is now fixed with the patch that rolled out during the node war channel maint on the 18th of May. Thanks.
