The Cave Fisher has this in its Offense section:
Ranged filament +3 (drag)
Special Attacks pull (filament, 10 feet)
I know wolves have something similar:
Melee bite +2 (1d6+1 plus trip)
This one is pretty self explanatory; the wolf gets a trip attempt as a free action on hit in addition to its damage.
So it seems that the cave fisher gets a drag attempt in addition to its... nothing. The weird thing is that it also seems to get a free pull attempt:
A creature with this ability can choose to make a free combat maneuver check with a successful attack. If successful, this check pulls a creature closer. The distance pulled is set by this ability. The type of attack that causes the pull and the distance pulled are included in the creature's description. This ability only works on creatures of a size equal to or smaller than the pulling creature. Creatures pulled in this way do not provoke attacks of opportunity and stop if the pull would move them into a solid object or creature.
Am I missing something here? Can a cave fisher drag AND pull?
