Lurking Familiar
( Player's Handbook II, p. 80)[General]
Your familiar hides within the folds of your robe or takes cover behind you as your opponents close in. When it moves to attack, its sudden appearance might catch your foe by surprise.
Prerequisite
Combat Familiar (PH2) , arcane caster level 6, familiar,
Benefit
If your familiar occupies your square, it gains cover against all attacks. As a consequence, it can make a Hide check to avoid your foe's notice. If your familiar then leaves your space to attack an opponent, it gains the normal benefit for attacking from a hidden position.
