Kingdoms of Amalur: Re-Reckoning · Skill
Mercantile
Mercantile improves buying and selling terms by letting the character buy for less and sell for more.
How it works
The Skills page states that Mercantile improves the character's ability to buy for less and sell for more. It gives no price formula, numerical effect, or level-specific changes. Skills can be upgraded to level 10, but that general progression limit does not establish how Mercantile's transaction effect changes across its levels.
