Lichdragon Fortissax¶

Lichdragon Fortissax can only be accessed if you speak to Fia at the Prince of Death’s Throne and choose to give her the Cursemark of Death. Then, you’ll need to speak to her three separate times following this interaction to then unlock the option to ‘Enter the Deathbed dream’.

You’ll then fight Lichdragon Fortissax, which is a huge four-winged dragon. If you want The Age of Duskborn Ending, you’ll be required to defeat Lichdragon Fortissax.

For defeating the Lichdragon, you’ll earn the Remembrance of the Lichdragon and 90,000 Runes.
