With Lullaby, it took me a few levels before it seemed to work well. I was
using it last night in Permafrost too. I found out the best way is to equip
lute, then back out of the fray. This way when they do wake up, they'll
attack a tank, not you, until they go back to sleep the next pulse.

I used to try singing lullaby while wacking them with my swords, and that
did nothing but get them really pissed at me.
