Deep Meditation #Microfeats.
Deep Meditation. Prereq: Ki. You can spend a point of ki to enter a deep meditative trance as a full round action. While in this trance you may reattempt one failed Knowledge check each hour, diseases and poisons do not progress and you may attempt a concentration check (d20 + Wis + HD) to overcome one disease or poison each hour (DC equal to the save DC), you use only 1/10th your normal air or food consumption, and you are treated as sleeping except you take no penalty to Perception checks and may choose to awaken as a swift or immediate action in response to any successful Perception check. #Microfeats.
#Microfeats are experimental feats we have in playtesting or development (and may well change before they ever get used in a product – or may get cut entirely). Today’s microfeat is inspired by http://paizo.com/products/btpy9065?The-Genius-Guide-to-the-Talented-Monk
