Longer than a quarterstaff, a longstaff is much more difficult to use, but skilled wielders are better able to protect themselves from multiple attackers when fighting cautiously.
If you are proficient with the longstaff and you fight defensively or employ the total defense combat maneuver, you cannot be flanked for the rest of the round. This benefit also applies if you are proficient in the weapon, have the Combat Expertise feat, and shift at least 2 points of your attack bonus to Armor Class for the round.
The longstaff is a double weapon and a special monk weapon just like the quarterstaff.
Characters proficient with the longstaff can treat it as a quarterstaff for the purposes of the following feats
|Exotic Weapon - Melee|
|Two-handed weapon. See the description of this weapon for special rules.|
Preferred weapon of: No known deity.
