Looking for stuck merchant.

[Moose]

I fortunately got the Guardian Shrine spawn but i'm missing the curio and rest of the set to complete it. Would be great if I could get into a world with it and buy/find em.

If you want the full Radiant Set, make sure to buy both parts from the merchant before you go for the helmet, as opening the Guardian Shrine that contains the helmet summons a Root Horror mini-boss that, will move to where the Stuck Merchant is and kill her, making both the chest and the legs pieces unobtainable and requiring you to reset the world.
To circumvent the high cost of the Guardian's Ring, you can open the Guardian Shrine to let the Root Horror kill the merchant. The ring should be next to her corpse.

This is from the wiki.

If I see her in my world I'll let you know
