- Talk to Healer Alezan
- Complete the quest
While exploring Cryptwatch Fort the Vestige will find a hastily scribbled note at the near end of the dungeon. It also cantains a message with orders to the Red Rooks.
"Copy this message and pass it around: The Bloodthorn cult may betray us. They aren't doing well and we think they may be getting desperate. The note contains recipes for salves and potions to help fend off theor festering magic. Be prepared."
Head outside and follow the marker to find Healer Alezan at Lion Guard Redoubt. He thinks it's interesting as they suspected the Red Rooks of collaborating with the Bloodthorns. They can use this to their advantage now and the healing recipes will come into good use.
