RG Live WotLK 3.3.5a

https://wow.gamepedia.com/Frostsworn_General

Pulling the General back to the Altar in the first room will cause him to be incapable to summon the reflections, however he will still cast it. Aswell as this, defeating the Frostsworn General without allowing him to summon the reflections will cause the players to be able to see their reflections, frozen in ice.
Prior to Patch 4.0.1, if a player performed the above glitch, and used an emote at their reflections in the ice, the target would be called Spiritual Reflection. However with 4.0.1, it now correctly says the player's name.

There's an exception where they should not spawn.
As of right now, they spawn (with at least 2 players in the group) and despawn again after about 1 second.
