Trap Sense

While Obsidian has not confirmed the existence of trap sense in NWN2, it is a class feature of both the barbarian and rogue class which have been confirmed.

3.5 Trap sense
The character gains an intuitive sense that alerts her to danger from traps.

This feature provides a bonus on reflex saves made to avoid traps and an equal dodge bonus to AC against attacks made by traps. Trap sense bonuses gained from multiple classes stack.

e.g. A level 6 barbarian has a +2 bonus to reflex saves and a +2 dodge bonus against attacks made by traps.
