In Elden Ring, you’ll find a wide range of characters that will share their plight with you, most of these will have Quests that span multiple locations. This page will detail where you can find Roderika and complete her Questline.
First Meeting - Stormhill Shack
To begin the Quest, you’ll need to first locate Roderika, and you can do that by heading to the Stormhill Shack Site of Grace, this is found by following the road north from Gatefront Ruins. Once you find the shack, you’ll find her sitting on the floor. Speak to her to obtain the Sitting Sideways Gesture and about her plight, and the ominous spider at Stormveil Castle, it seems Roderika is the only one remaining of her group. Speak to her several times and she’ll hand over the Spirit Jellyfish Ashes, before dropping a hint about how people become a Chrysalid when attached to the spider. This is a hint about the next part of her Quest.
You’ll need to venture into Stormveil Castle and progress until you reach the room to the side of the Grafted Scion. In this room, you’ll find a pile of corpses and on the top, you’ll be able to loot the Chrysalids’ Memento. With this safely tucked away, return to Stormhill Shack and deliver it to Roderika to have her move to her next location in Roundtable Hold.
Second Meeting - Roundtable Hold
Once you return to the Roundtable Hold after giving her the Chrysalids’ Memento, you’ll find her near the hearth. Speak with her to obtain a Golden Seed as way of thanks. She’ll stick around here lamenting her purpose in life for a while. Leave here there for a while and go and speak with Smithing Master Hewg and you’ll be able to ask him about Roderika (you may have to leave and return to the Hold to prompt this).
Travel between the pair, asking them questions about each other and eventually Roderika will agree to some tutelage from Hewg. The next time you return to the Hold, you’ll find that Roderika has now set up shop near Hewg and will offer her services allowing you to upgrade your Spirit Ashes.
