Another insanity thing. Last time it was the mapmaker, and we gave those confusion, right? I'm thinking shaken might be appropriate here, but a gaze attack is still more serious than any of the other familiars. Perhaps it takes a standard action and targets a specific individual, like a vampire's dominating gaze?
Something like this, then?
Malevolent Gaze (Su): A durocib can unsettle an opponent simply by looking onto his or her eyes. This is similar to a gaze attack, except that the durocib must take a standard action, and those merely looking at it are not affected. Anyone the durocib targets must succeed on a DC X Will save or be shaken for xdx rounds. A creature that fails its save must make a second DC X Will save or fall instantly under the durocib's influence as though by a charm person spell from a xth-level caster. The ability has a range of 30 feet. The save DC is Charisma-based.
Sorry, I do not know what my trouble is today. Not enough sleep, maybe.Shaken is already the weakest of the fear effects, freyar. I suspect you're going in reverse.
Usually slow and deliberate in its movements, the durocib is capable of sudden darts and lunges, and has an uncanny ability to sense the intent of an enemy an instant before the enemy takes any action. Because of this characteristic, the durocib makes saving throws as a 7th-level thief. The creature has in addition a number of thieflike abilities, all performed with the same chance of success as a 7th-level Halfling thief. They can move silently, hide in shadows, climb walls, and detect traps; the latter ability is limited to snares and pits only. Because of their keen senses, durocibs are never surprised and can surprise others on a 1-4. Though they are clever with bolts and latches and can use simple tools, durocibs are unable to become skilled with weapons.
