Meditation Incense
　This tiny cone of incense provides remarkable powers of focus when burned during meditation. If breathed for one minute, it gives +2 to Meditation or any skill that takes Meditation as a prerequisite. The effect lasts for the following hour.
The incense also reduces the number of turns of Concentration maneuvers required to use any nonspell skill by half during that time. The smell does linger, though; scent-based trackers are at +4 to follow the user’s trail for the next day.
　A cone of meditation incense is $400, negligible weight.
