These guys are definately level 75-78. At level 72 soloing these guys the lowest exp I would get was 200. Got 300 for the toughest. Dinged 73 and am now getting 160-280.
Actually she's standing by the ones that do not aggro you on site. The ones in the "blue cubby holes", like Xanthan said, will aggro you on sight. The rest you can pass with ease. They will however aggro to magic.
The ones in the blue alcoves aggro SOUND, not sight. They all aggro magic like all doll mobs do.
When traveling around in the gardens, just hug the outside edge and you don't need sneak or invis. You pretty much can't cast anywhere except right at the start portal, so make sure you bring those oils!
Actually, I've just been agroed by one not in the blue platforms. I hit the first portal into Gardens, went straight forward past the path with the blue platforms, turned right to explore, and one started hitting me (he was wandering around until I got near him).
Sounds like you might've run into one that aggroed someone else from a blue alcove and was on his way back home. I believe they would still aggro in that situation. Could be wrong, though.
EDIT: Said something about casting magic, then noticed your jobs and realized that was very unlikely.
If you look she's standing behind it and the pic is of it's back. I'd think she got away unharmed as long as it didn't turn around before she was done.
The mobs in the blue alcoves have true sight, it would not have mattered if she had invis on or not. The mobs outside the alcoves will not aggro to anything but magic ... the only exception is during cloudy weather when bomb-type mobs spawn, and those aggro to sight and magic ...
yes, the Groundskeepers in the charging stations (blue cubby holes on the sides) will aggro by sight. I walked up for a closer look and to my surprise the thing jumped down and wailed on me. It was hitting me for 208 a hit, I didnt make it far. Be careful
