Master Explorer (Ex)
A Pathfinder delver adds half his class level (minimum 1) as a bonus on all Disable Device and Perception checks. A Pathfinder delver can disable intricate and complex traps in half the normal amount of time (minimum 1 round) and open a lock as a standard action instead of a full-round action. He can always take 10 on Disable Device and Stealth checks, even if distracted or endangered, and he can use Disable Device to disarm magical traps.
