You draw a diagram on the ground and call on a minor fiend to assist you.

Daily   ✦     Arcane
Standard Action      Personal

Requirement: You must use this power during an extended rest or a short rest.

Effect: You spend a healing surge but regain no hit points. Instead, you call forth the awareness of a fiend and ask up to three questions of it. For each question, make a check with a bonus of 5 + one-half your level + your highest ability modifier against a DC the DM secretly sets.
    On a successful check, the fiend gives a truthful answer. If the check fails, or the DM decides the fiend cannot know the information, the answer is a lie.
    You also gain a +2 power bonus to all knowledge checks until you reach the next milestone or take an extended rest.
