1. if u dont have subclass make another and u will get permanent paulina R grade twilight for corresponding class so for robe and staff u can pick mage subclass, same thing for your archer make new subclass and lvl it from quest at Tarti in Gludio town if u want those subclasses skill but if u already have it will stay if u reset 1 subclass last time I check before new update
for sure u have done subclass quest coz u have dualclass so if u have 2 more subclass reset each at a time, those armor and weapon automatically given to u at lvl40 any class
2. adventurer questline currently bugged so for adena u might want to check Pavel Ruins, Stuttgard
and for xp I suggest Silent Valley, Aden
