Summary: The skill, Demonic Confusion of Advent, for Heavenly Demon Holiest Does not work for several minutes after it's cooldown. Steps to Reproduce: Click the skill right after it finishes cooling down. Frequency: 8 out of 10 Severity: 5 Additional Notes: Sometimes the skill works flawlessly other times the skill refuses to activate well after the cool down. I think it could be a distance problem. But I don't know. This problem happens to me with the first level of the skill.
Thank you for your report. We have confirmed that this skill bugs when you target a mob before this skill has cooled down and will report it to our developers. In the mean time, this issue will not occur if you target a mob after the skill has cooled down and then you use the skill.
