We managed to kill Garalon last night! I have a lot of videos of us failing, but near the end of the raid night we managed to kill him. Hopefully we have the strategy and skill to continue killing him in the future. We actually did a quick attempt on the next boss too before calling it.
You can see our success above! Funny that I just posted about Garalon, too. I’ll consider this a birthday present from Blizzard and my guild.
