There's a new Tip of the Week being shared with the EverQuest community on the official forums -- kill stuff this weekend. Okay, so most players would have been killing stuff anyway, but the reason for the tip comes from the fact that there's more experience on offer than usual:
EverQuest adventurers will be surrounded by a magical DOUBLE experience increase. And double XP means 100% extra XP, or 200% XP... Whichever way you want to look at it, that's a lot of XP! Happy adventuring!
