Realm First! Sinestra
- Realm First! Sinestra
- First guild on the realm to defeat Sinestra in the Bastion of Twilight on Heroic difficulty while in a guild group.
Like other realm firsts, there will be a server-wide notification when this achievement is completed. However, it is awarded as a guild, rather than individual, achievement.
