hmm ok my 2 cents on lull/harmony/mez.

I have a 32 Paladin (sooth)
I have a 32 Druid (harmony)
and an 8 enchanter.

what I have done to pull camps is use both lull and mez to break the camp.

Harmony reduced agro range to near 0, and extremely rare if any save.
(ourdoor only though)

Lull/Sooth/Calm will reduce agro range depending on level of spell.
Obviously Sooth reduces the agro range better than Lull. When they resist
they don't always agro, most of the time they do.

Mez has already been described.

ok, now what I have done for some camps is to Lull everything and pull. Now
if one saves and pulls a partial camp, I mez the ones that come after us.

*notes on lull* Make sure you Lull/sooth the furthest back. If an agro
most monster past a lulled one.. they will agro as well. If you do it
right, and it works, lull the back ones.. pull the front, and mez the ones
agro if more than one come.

Harmony is the best though, but playing all 3 characters, I have used them
all.. Lull and mez is a poor mans substitute for Harmony. I have used the
combo successfully in an indoor dungeon though. Lull one and pull another..
if they resist lull then mez till the tanks take them out. BTW lull line
does not work on an agro mob. Good luck, has anyone else done it this way?
