Hypnotism

The gestures of the illusionist, along with his or her droning incantation, cause from 1 to 6 creatures to become susceptible to suggestion (see the third level magic-user suggestion spell). 

The suggestion must be given after the hypnotism spell is cast, and until that time the success of the spell is unknown. Note that the subsequent suggestion is not a spell, but simply a vocalized urging. 

Creatures which make their saving throw are not under hypnotic influence.
