Additionally, Uncanny Dodge in NWN2 does not protect against attacks from hidden creatures.
However, the in-game feat lacks any mention of these limitation and gives the incorrect interpretation that a character with IUD should be immune to many sources of Sneak Attack.NWN2 wiki wrote: The in-game description of this feat is incorrect. As per the Game Manual, this feat does not include attacks from hidden creatures. Successful attacks from stealth will not be affected by Uncanny Dodge.
Uncanny Dodge does work, but only as described in the Game Manual (not the in-game description shown above) - it is only effective against invisible attackers.

This feat is somewhat misunderstood due to its incomplete description: it will not give the user blanket immunity to sneak attacks, but it does render the user immune to sneak attacks that are delivered via flank attacks.

A suggestion for corrected texts could be as follows. Using the game-manual text cited by the wiki would be ideal, but I'm unsure what it is.Current Text wrote: Uncanny Dodge
The character retains his Dex bonus to AC, even if caught flat-footed or attacked by a hidden or invisible creature.
Improved Uncanny Dodge
A character with this feat cannot be the victim of a sneak attack unless the attacker performing the sneak attack has at least 4 or more levels in classes that give sneak attack bonuses (such as rogue or assassin) than character levels of the defender with this feat.
