is it possible to pick up clothes better than the more expensive and that in the guide?
for example instead of AoA put Ulles Ulles Cap(Vesper Card) and anything else
or it will be bad for the multiplicity of stat build?
First of all a Vesper card would be useless since Falcon Assault is not magic damage.
The guide is good but focuses on high damage due to rapid fire which means that a fast internet connection, PC and player is needed.
In terms of damage output from dex, AoA is the best headgear yet.
On the other hand since you lack a shield, I would recommend any damage reducing from demi-human like PooPoo Hat.
If you're rich enough or able to finish the quest, Large Baphomet Horns would be awesome.
Ulle's Cap is good also but not with a Vesper Card, any int, dex or agi card would be well.
