i think thurvokun only fires when something hits you in melee range (7 meter or less), cause archers cant proc it from a distance
its probably a related issue on the dragon, because the distance measured from your character is the center of the enemy model, which is one of the reasons why tethers dont usually work well on dragons
i have my main house (grand topal hideaway) listed in the housing tours, it has multiple target dummies, scribing altar, and grandmaster stations (fully filled out with current game), as well as almost every antiquity furnishing on display to preview them
in progress: acquiring mundus stones (currently only have the thief)
