—That’s Odd (Methodology): When you enter a new location, such as a room or corridor, you immediately notice one thing out of the ordinary. The GM determines what it is, or whether there's nothing reasonable to pick up, skipping obvious clues that can be easily noticed without a check or specifically looking for them. You learn only that an area or object is suspicious, but not why it's suspicious. For example, if you entered a study with a large bloodstain on the ground, the bloodstain is so obviously suspicious it's evident to you already, so the GM might note that there's something suspicious about the desk drawer instead. You would then need to investigate the drawer further to find out what specifically is out of the ordinary. That's Odd doesn't reveal whether creatures are suspicious.
You don't typically get any benefit when you leave and come back to a place, though if a major change has happened there and time has passed, the GM might determine that you do.
—Streetwise (Background): You know about life on the streets and feel the pulse of your local settlement. You can use your Society modifier instead of your Diplomacy modifier to Gather Information. In any settlement you frequent regularly, you can use the Recall Knowledge action with Society to know the same sorts of information that you could discover with Diplomacy to Gather Information. The DC is usually significantly higher, but you know the information without spending time gathering it. If you fail to recall the information, you can still subsequently attempt to Gather Information normally.
—Gloomseer (Heritage): Gloom holds few terrors for you, and the pall of darkness over Nidal has made you comfortable in dim light. You gain low-light vision.
—Trap Finder (Class): You have an intuitive sense that alerts you to the dangers and presence of traps. You gain a +1 circumstance bonus to Perception checks to find traps, to AC against attacks made by traps, and to saves against traps. Even if you aren’t Searching, you get a check to find traps that normally require you to be Searching. You still need to meet any other requirements to find the trap.
You can disable traps that require a proficiency rank of master in Thievery. If you have master proficiency in Thievery, you can disable traps that require a proficiency rank of legendary instead, and your circumstance bonuses against traps increase to +2.
