Erm? I don't get what you're typing exaclty... But in a cheap, simple summary:
1) Go into a "zzz" zone until it says You Are Now Rested.
2) Use your rod thingy to turn into a Furbolg
3) What I did was charge an enemy in Rested and... it untransforms you when you enter combat after like 2 sec.
4) And voila, kill it, free XPs
5) Then I redid it..except not in Furbolg and then I turned into a Furbolg mid-combat
Voila Again
I got it to work for 3 kills and then I couldn't do it anymore. I went back to the inn and although the bar showed that I was rested it said that I became rested again. The second time I was able to get 7 kills with double the xp. It might just be the timing.
