Charisma

Charisma improves the buy/sell prices at Space Stations. It doesn't affect the prices at regular shops (like Terramart) or prices of Trader NPCs.

Some armors have bonuses/penalties to charisma.

Kirhos have +21% to charisma ("Great Traders" bonus), while Pharitu have -10%, and Mantizi and Thelusians have -25% ("Poor Traders" penalty).
