Pending nightly restart, Detect Hidden has had an action added to it in the skillbook- Disarm Trap, used to disarm trapped, unlocked chests. Details are as follows:

• To disarm a trap, the player must have at least 80.1 Lockpicking and Detect Hidden. Disarm Trap provides a chance to disable traps on chests that are not locked (e.g. have been lockpicked). The success chance is based on both Lockpicking and Detect Hidden skills.
• While 80.1 will allow you to disarm chests up to level 4 (Cleverly), to disable traps on level 5 (Devious) chests, you must have 94.1 in both skills.
