Legerdemain Skills in Elder Scrolls Online are part of a special Skill Line that is acquired by stealing an item from an NPC. This Skill Line was added in Update 6 as part of the Justice System. Players will rank up this Skill Line by stealing items and selling them to Fences and picking locks. You get 1, 2 or 4 points towards Legerdemain depending on the difficulty of the target. At level 1 you can only Fence 50 items per day and you gain 1 point towards Legerdemain per item Fenced no matter the quality. You gain 1 point for picking simple chests, 2 points for intermediate chests and 4 points for advanced chests. Silver Lock Boxes will contain the best loot, but are rather difficult to get to as NPCs regularly guard them.
