These seem to argo sight in Crawlers Nest. I was standing still reading LS chat, when my invis and sneek wore off. Didn't move.... so I didn't make a sound. And the thing comes over and beats me down.
if you don't move sound aggro won't aggro, unless their path they are walking takes them through you. it will look like they aggro you a little before because of the slight delay from the sever to your screen.
Fairly new post, so I figured I'd reply. You can still get sound aggroed whether or not you move. Movement has nothing to do with getting aggroed via sound.
There are only a couple diffs between sound and sight aggro. For one, sight is directional and sound is omni-directional (this is also factored with links - i.e. you won't get a link from a sight mob if the potential link is facing the opposite direction). Also, sight aggro range is noticably farther than sound.
I really wish S-E would lower the chance of sound aggro if you don't move, but not gonna gripe :P.
The drop rate for these in the Crawler's Nest is absolutely ridiculous. I sometimes get 6 items, ranging from multiple skins, tails, and eggs to one of each plus crystals and seals. I've been soloing these with my lvl 50 bst and I've made ridiculous loot here recently.
Oddly enough the crawlers nest Labyrinth Lizards aggro, but the gustav tunnel Labyrinth Lizards do not(Con T to VT so I wasn't to strong for them to aggro) Gustavs are also a lot weaker.
