From September 2nd to September 8th, it's time to get buffed!
Talk to any Guide in town for an All You Can Eat Buffet of buffs! Just visit the Guides and say "Buff Me!" and they'll do just that! Enjoy Attack Speed, Cast Speed, and Movement Speed buffs that are both delicious and nutritious. Plus, they'll fill you up for over an hour, so you have plenty of time to savor them in a dungeon party. Dig in!
