I think this is true of all sorts of gear and I gotta say, I don't really understand the loot system. It seems that most of the rarities are found in low-level Barovia instead of higher level areas.
yea I do not understand that either...No wonder high levels hang around the outskirts....
This does not make sense.
In any case, spot items regularly drop in perfidus and sometimes coa mine. Likely on ghakis. Stealth gear once dropped in perfidus but it may be non existant or extremely rare. I believe stealth items also drop in hag locations, but i dont know how often that happens now.
Since i have hit perf, the desert, and coal mines the most out of those places, i have collected about 6 +5 spot helms and 8 spot rings. I have found maybe 4 inza daggers. They seem to have dissapeared from coal mines.
Needless to say, the drop split seems pretty lopsided on the side of spot gear.
