Persuasion

Persuasion is the first support or non-combat skill and is a combination of the classic speech and barter skills. In contrast to science and engineering, its effects are mostly passive. Persuasion affects the selling price of a player's item, but not the value at which merchants sell their items. On top of that, the skill also factors into the Zone Control and quest rewards and generally increases reputation gain. Persuasion is primarily raised through bartering with an npc.
