I got in Verdistis a while ago. In the market district in Rivertown, there was a sewer entrance there as well. Tried it and figured it's a great way to level up like the orcs. I'm playing on Normal difficulty if it makes any difference.
I have in my memory seeing another sewer entrance here in Verdistis. But now that I'm searching for it again, I can't find it. I could've sworn I saw it somewhere sometime. I really did. Where is it??
I did a search on google and couldn't find a single entry that shows it.
There are 2 entrances, near the Verdistis teleporter pad, in the NW corner of the park (north of Corinna's house and south of the merchant's guild), and the other just across the path from the SE corner of the park.
