If you're going around Jugner, you will need both sneak and invisible if you wish to avoid detection from Lobison. They are bigger badder Gnoles who stand on their hind legs and hit like a mack truck @ Hundred Fists speed.

I didn't see an Lobison, but I did see tons of Decrepite Gnoles. They were all T-VT at least. Though I have the feeling something sparks a change between them to fight on all fours or their hind legs, possibly having to do with moonphase. On all 4s they didn't seem that dangerous (beyond the usual dangers of a 75-ish mob) so perhaps the Lobisons are their transformed state and far more powerful.

Pieste are sight aggro. And Idk how you ran into the Gryphons and the Wyverns in Grauberg; taking the path to and from Bastok that I go, I NEVER run into them.
But yeah, the Hippos are TS still..

Good to know, on both accounts. And I took the shortest path I could find through Grauberg, which meant cliff jumping down one way waterfalls. Between the first and second drop there was a bunch of both just roaming around.

Also, any idea what Wivre aggro too? I ran past a few VTs with no sneak and didn't get aggro, but saw one look at a few uninvised PCs and didn't aggro them either.
