Radiant Singer

I am Horde and just watched an Alliance raid do the event and I did not receive the achievement. I had the buff going and was on the lower level with the flame targeted. A different Horde player got it though so the achievement must be buggy or have a strict range to it.

I tried getting it a second time, again with an Alliance raid. I had the buff going, had the flame targeted and was up the stairs with the raid. I still did not receive the achievement. When I spoke in /say no other Horde player said they got it.

Third attempt, buff going, up the stairs, flame targeted no credit but 48 people got the achievement. I'm not sure what gives observers the ability to get the achievement. I read someone say you need to be in a raid group so I will try that next time.

It looks like you absolutely have to be in a raid group to receive credit. On the fourth attempt I made a raid group with a couple people nearby and received credit when the Alliance group finished.

Solved 3.30.26 by the Secrets Discord. This is a part of the process of completing the 11th orb for the Felcycle mount.

This Feat of Strength is related to the Ratt's Revenge Secret, which was used to obtain the Keys to Incognitro, the Indecipherable Felcycle, but it is not required for you to have done any of that chain.

At this time, in order to trigger this achievement (which, as you can see below, may also be obtained by standing NEAR a "performing" raid group), you need a 40 man raid group, preferably using an addon to coordinate the actions of the many "singers".

The data for this was compiled over several weeks by a multitude of players who had obtained the Oddsight Focus. There were 1000 combinations of Singers and Actions that were charted and eventually plugged into the addon.

Once a raid is assembled at the Divine Flame of Beledar each participant must target the flame. The raid leader begins the "song" by bowing to the flame. At each subsequent bow by the raid leader, each "singer" must perform a specific emote, that is determined by the spreadsheet whose data was fed into the addon.

The achievement will only happen if there are no more than 2 errors in any given "measure", and only a maximum of 15 errors overall.

There are 25 measures in total that must be performed, with 2 progress bars tracking the Harmony and Discord. Once completed the Feat of Strength is awarded to all members of the raid, as well as a few bystanders.
