you can also use the shrouds to solo a ldon. get two folks to shroud down 10 levels, get the adventure, and go to town--you don't shroud at all. i'm not sure, but i ithink as soon as you get the adventure you can disband. i wait until zoning into the adventure to disband.
wasn't too bad at 65 with the right AA on a collect. at 67, mobs hitting a tad harder and slow down the adventure significantly.
