Ready Check is a column focusing on successful raiding for the serious raider. Hardcore or casual, Vault of Archavon or Ulduar, everyone can get in on the action and down some bosses.
This is the show stopper. The big guy, the final countdown. Yogg-Saron is the last normal boss in Ulduar. (The only other dude is a freaky guy made from stars. Let's stick to the Old Gods here.) Yogg-Saron is the second Old God raid boss in the game, and shares an important dynamic with his predecessor: in-order to kill Yogg-Saron, you have to go inside him and fight a vital organ. Pretty freaky, huh?
Yogg-Saron is actually my favorite fight thematically. Perhaps as a purposeful shout-out to game mechanics from the Call of Cthulu, your raid members will have to manage a buff called Sanity. That dynamic was a signature, revolutionary aspect of the tabletop game, and Blizzard uses it very similarly in this boss fight. At least, I hope it's purposeful. It's possible they were simply inspired by Lovecraft's stories the same way that tabletop designers were. Still, I prefer my little world where those guys threw some dice and stared at their SAN score.
Anyway, let's get to talking about the boss fight.
