The rogue can suppress a memory of a single encounter, adventure, or experience by concentrating for 1 minute once per day. This negates any dread or insanity gained as a result of that memory. The rogue can suppress only one memory at a time and the effects resume immediately when it is recalled with another 1 minute of concentration. The rogue doesn’t know what memory was suppressed or why she suppressed it until she recalls it. This can allow a rogue to lie more easily by removing contradictory knowledge, granting a +10 circumstance bonus on a related Bluff check. Even if the rogue doesn’t consciously know she is lying, she must still make a Bluff check to convince someone she’s telling the truth. Magic cannot detect such an unwitting lie except by digging deeply enough into the target’s mind to know she has this rogue talent (for example, with dominate person), and even then, it does not reveal what information was hidden or whether it contradicts what the rogue claims unless the magic also compels the rogue to recall the memory.
