Overview
How to get the Charm of the Red Maiden in Betrayer (spoilers!)
First gift
The Charm can be aquired by giving gifts to Allison.
You need to give her two items with the correct dialog choices, then talk to her again.
Found in Sentry Post (see map below)
(The Wood Carving has to be shown to Samuel Mallard in Sentry Post before you can give it away)
Dialog choices with Allison:
You: I have a gift for you.
She: What is it?
You: This crude figure that Samuel Wright carved.
She: It is grotesque. Why are you giving it to me?
You: In case you wanted to make something with it.
Second gift
Found in Forbidden Wilds (see map below)
(The Cloth Scrap has to be shown to Clement Wright at the Ambush Site in Forbidden Wilds and Allison Markley in Fort Hope before you can give it away)
Dialog choices with Allison:
You: I have a gift for you.
She: What is it?
You This scrap of cloth from your cloak.
She: Why are you giving it to me?
You: Maybe you can make something with it.
Now once you start a new dialog with Allison she’ll give you the Charm of the Red Maiden.
That’s it. Have fun playing!
