Philter of Love: This potion causes the individual drinking it to become charmed (see charm spells) with the first creature seen after consuming the draught. The imbiber may actually become enamored if the creature is of similar race and of the opposite sex. Charm effects wear off in 1d4+4 turns, but the enamoring effects last until a dispel magic spell is cast upon the individual.  

Philter of Persuasiveness: When this potion is imbibed the individual becomes more charismatic, gaining a bonus of +5 on reaction dice rolls. The individual is also able to suggest (see the 3rd-level wizard spell, suggestion) once per turn to all creatures within 30 yards of him.  

Philter of Stammering and Stuttering: When this liquid is consumed, it will seem to be beneficial—philter of glibness or persuasiveness, for instance. However, whenever a meaningful utterance must be spoken (the verbal component of a spell, the text of a scroll, negotiation with a monster, etc.), the potion's true effect is revealed—nothing can be said properly, and the reactions of all creatures hearing such nonsense will be at a -5 penalty.
