A psion is a person who uses the power of the mind, or psionics, to influence objects, rather than magic. Often colloquially referred to as "mind mages," they draw their powers from their own consciousness using methods that must be replenished, or can be innate, as in illithid, aboleth, kalashtar, psiforged, and drow practitioners. Although it is not fully known, this gift is an inherited trait and is subsequently genetic. That being true, it is rare to find a psion in races where psionic powers are not the norm. Despite their rarity, a master psion can be quite powerful. Not being held to the need for gestures or spell components a psionicist is awarded the advantage of surprise in many cases, and thus may hold an advantage over a magic user or a priest. However, in many of the humanoid races, manifestation of psionic power can lead to a secondary display that can often give the psion away. These displays may include, but are not limited to, visual, auditory and olfactory senses being emitted. As an example, if a mind mage manifests a simple charm, or mind reading power, a low droning sound may be heard. Similarly, a polymorphic manifestation may leave the odor of saffron and ginger.
As most of these secondary displays are difficult to observe, most tactics used by psions can prove surprising to non-psions. If caught unaware, or in the case of a powerful mind mage very aware, a psion can be most powerful. Psionic powers can range from devastating mental attacks that dominate an opponent, to physical ectoplasm constructs and a fate link that can inflict damage linked between individuals. That being said, such manifestations can take a great toll. Inate practitioners such as illithids, aboleths, kalashtar, psiforged, and select drow can grow weary and unfocused if they over-extend themselves. Practitioners of other races can deplete their store of power in short order if unskilled and will have need to replenish those powers.
