An entangled character also takes a –4 penalty to Dexterity, which may affect his attack roll. The defender loses any Dexterity bonus to AC. This bonus doesn’t apply if the target is blinded. Most ranged weapons can’t be used while the attacker is prone, but you can use a crossbow or shuriken while prone at no penalty.

That defender loses any Dexterity bonus to AC. Treat the defender’s Dexterity as 0 (–5 modifier). Rogues can sneak attack helpless or pinned defenders.
