Since some people have asked about where to farm Ugdenblooms, I made a map of the route I’m using.
In this run I only target the tree type enemies that have a chance to drop them (especially the Hero ones do). Most other monsters are skipped except other star enemies.
Next, there are 2 Rotting Stumps in this run that have a chance to drop 1 or 2 Ugdenblooms.
I tend to get at least one per run and it takes 3-4 mins per run, so you can do the math.
The run also passes by 3 different spawn locations for a Treasure Trove so you have a very good chance of running into one.
This is a good way of getting the new Blueprints or just Legendary items in general.
I rounded it up by visiting some areas I know 2 purple bosses spawn for extra loot. You need to have the quest The Feast for Handarroth to spawn though.
Lastly, it also passes by 3 spawn locations of the Beast Nemesis, I skip him though since my char is still too weak to handle him.
Map below and a video for those visually inclined.
Ignore the weak char, I’m not nearly done farming yet.
