Hard to say right now not knowing what it drops. If like the wisps they help alot with hidden foreest event. But with fangbeasts needed and spawns from farmhouses. That helps with regular goals. Like tradesmen and monster hunts. Kinda ****ing two birds. But will all depend on how productive the dragon is.
Guess i shoulda waited..much more informative post above. Didnt realize the drops were known yet. My bad
