Dark Souls Remastered | Ingward full dialogue, Key to the Seal, Resist Curse & Transient Curse

Ingward is in New Londo Ruins. It is necessary to speak with him to obtain the Key to the Seal. He also has two inventory items you can purchase, including Resist Curse (a Sorcery item) and as many Transient Curses that you want, which I recommend having plenty of since they're necessary to kill the ghosts and expire either when you die or after only 5 minutes.
