You master the Limbo-native neraph martial art of motion camouflage for your thrown weapons.
Prerequisites: Dex 15, Knowledge (the planes) 5 ranks.
Benefit: You can throw a weapon in such a way as to fool your foe into believing that the thrown weapon is not moving closer, or moving closer too slowly to be an effective attack. A victim of your Neraph Throw attack may not apply its Dexterity bonus to its Armor Class. All conditions that pertain when a foe cannot apply his Dexterity bonus to Armor Class also pertain to the Neraph Throw attack, if any (for instance, a sneak attack also could be made with this attack if you can make such an attack).
Once you have used a Neraph Throw attack against an enemy (regardless of the attack’s success), any later attempts to use Neraph Throw against that enemy in the same encounter automatically fail. Once a foe sees the attack in action against himself, the foe can discern it for what it is for the duration of that combat.
Special: Neraph Throw has no effect against foes who can’t see you.
