Samera has posted some cool news for people considering coming back and some cool stuff for those currently play:
Dungeons & Dragons Online: Stormreach™ would like to welcome back our former players for a very special weekend. We can't wait for you to see all of the amazing things that have happened since you left!
From Friday, March 16th through Sunday, March 18th we will be celebrating by offering an additional +50% XP and +1 to loot for ALL players. There will also be special live events throughout the weekend so keep your eyes open.
Also, if you haven't logged in for awhile, be sure to visit your trainer to take advantage of the new enhancement system! All of your previous action points have been refunded to you so that you can customize your character the way that you want.
If you still have the game installed, you don't have to re-download the game - you can simply patch. However, if you have lost or deleted the DDO client, or if you think the patch will be too large, please use the following files to obtain the most recent version of Dungeons & Dragons Online.
To assist our customers that are having trouble downloading one big file, we have broken down the download into five (5) smaller downloads. Please follow these step-by-step instructions to ensure you download properly.
Make sure you head over to the official forums and read all the details and how to download DDO.
