How do you befriend Big Boggart in Blackguard?
Once you have the necklace, return it to Rya, then head back to Boilprawn Shack and speak to Big Boggart again. Buying his Boiled Prawns makes him trust you. You need to speak to Rya and then retrieve the necklace for her from him by buying it from him. Afterwards, he’ll sell you shrimp while he’s still in Liurnia, but will move to the outskirts of Leyndell later on and sell crab as well after that point.
Can you save Blackguard Boggart?
You can save him by aggroing him before freeing Dung Eater from his cell. After he is aggrod you can go to Dung Eaters cell and free him then go back to Blackguard and approach him to get aggrod again so you can trigger Dung Eaters spawn. Once you’ve taken care of Dung Eater, return to Big Boggart and you’ll be able to loot the Seedbed Curse, along with Blackguard’s Iron Mask, Iron Ball, and Blackguard’s Bell Bearing. Note: If you don’t progress Dung Eater’s questline at all, Big Boggart will stay at the outer moat selling his goods.
