Crippling: While wearing this item, your ranged weapons are infused with binding power so that when targets are critically hit their movement is slowed by half.
Seeker +10: +10 Enhancement bonus to confirm critical hits, and damage (before multiplier) on critical hits.
Accuracy +15: +15 Competence bonus to Attack rolls.
Ghostly: Equipping this item causes you to become partially incorporeal. Your melee and missile attacks do not roll a miss chance for Incorporeal targets. Enemy attacks have a 10% chance to miss you due to incorporeality. Hide and Move Silently skills receive a +5 enhancement bonus.
These likely pack quite a nasty sting.
