yes, the possibility to make potions is even higher than in the old places.
There are beds in abandoned houses and one house (base) near the orc trader, incl a cupboard. And the orc Shaman has gold charms - though very expensive: 100000 gp. Kroxy is cheaper: 50000.

There are enough golden charms, the imps drop them, too.

My "base" was the house I described, and I had one teleporter pyramid there.
