Barter
Barter is a trade skill the guide calls useful but nonmandatory, advising a minimum of 50 and describing money as becoming less pressing later.
How it works
The guide says Barter is nice to have but not mandatory and advises a minimum of 50; it mentions 100 for characters with no better investment. It claims money becomes less of a problem once weapons are covered and says Barter reportedly affects caravan contents. The caravan effect is explicitly qualified as reported, not established in detail.
