I'm going to have a fix out for Nightshade Arrow soon. Might look through the skills later to make sure they've all got parenthesis in the right place.
One thing- the Lifeshield Robe's description mentions it blocks "almost all poison", but the arrows from the Dark Dryad are special cases and don't get blocked. It won't inflict the Poison condition, but it will inflict the stat debuffs, and Nightshade Arrow checks for those. That said, Antipoison will remove these debuffs, and Lasting Antipoison blocks them out entirely.
The student in Arkenvali Academy with too many papers will probably have some more dialogue later, when the related side quest line continues.
I originally planned to have a bigger battle outside the Earth Cave which Marissa had altered dialogue for, but that ended up not happening. She and a few other characters will get more dialogue with the next patch.
Genn and Marissa aren't related to Brill by blood. Since Genn and Marissa took her in and raised her after her father disappeared, Brill considers them family.
(Also, if you mention a certain character's alignment, make sure it's low enough in the text that you have to open up the comment to see it.)
