Play a hermetic mage with "psionic" spells.

I still do not like the idea of thoughtforms, but i can life with them. What i cannot life with is an Ally-Spirit for a psionic. That goes far beyond a simple thoughtform, since they do develop their own mentallity and personality. That would be like the psionic is creating a second self.

I rather do take an aspected magican and put them onto the sorcery path. This way i do have access to all type of spells that fit into the whole psionic thing. Like Combat-, Detection-, Illusion-, Telekinetic- and Controll Manipulation as well as Transform manipulation Spells such as the Barriers.

That way i still have an psionic without having to deal with Thoughtforms and watchers. Okay i do lose the projection but i can life with that one.

Yeah but I don't think the Psionic was introduced to be a viable PC. The Psionic was introduced as an attempt to provide an example of an awakened individual with a severe psychological problem that affected his magical abilities. The character was introduced to provide flavor to the Shadowrun universe. If someone actually wanted to play a psionic I'd try to balance it out by counting their denial of magic as one huge mental flaw.

Why is that? There are plenty of examples where 'psychics' either speak with spirits, banish them or call them up (as mediums). Typically, these are the spirits of the deceased, but sometimes they are demons or other kinds of supernatural entities.

I'd personally treat a psion as a form of shaman, while giving them a bonus on detection spells and a penalty on combat spells, and a domain choice similar to Raccoon (allowing either modern urban psychics, or back-woods hermits/monks).

Because a psionic is in my mind doing everything himself. He/She is focusing their own Willpower onto some effect. In Most cases it will be a instant effect or something that needs to be substained by their concentration, but not casting something that will "hang out" around them and await new orders.

Or having a "Thought" return and report its mission (speaking of Watchers) That just does not go with the psi thing and the focus of mentalpowers onto something.

To create a spirit, which are all cable of thinking on their own (maybe except the watchers), is like creating a second personality each time they cast something.

And no Psionic ever had contact with the Death or Supernatural Stuff. That are other people like fortunetellers, shamans, witches and this kind of people. Psionics do mindreading, levitation, mind- and sensetwisting.

I thought those were great. I also like "ancestor spirits," depending on the psionicist's "spin." A more psionicist with a gypsie angle, or an old school 19th Century mesmerist, might be more likely to summon the "ghosts of the dead." I also liked the Ally suggestion. A variant Ally for a psionicist might be a "spirit guide."

Okay, let's combine this with the idea of Mental Domains, and try to make a workable Psionicist that people might be interested in playing. I really don't see why psions have to get picked on; it's no more different from "normal" magic than an adept choosing his somatic way; the psionicist is just choosing a "mental way."

To start off, we'll get rid of that stupid idea about foci, and allow psionicists to bond whatever foci they want, in the same way that other magic users can. Foci tend to be crystals or expensive gems and such; their presence helps the psionicist, "harmonize his thoughts," or whatever.

The idea I'm going for here is that, to the Psionicist (psion for short), there are four basic emotional states. Of course there are more emotions, but these are the most primal, the ones powerful enough to have their own existence seperate from the metahuman mind. There are four basic Mental Domains: loosely described as Love and Hate, Rationality and Fear. Rather than physical places like shamanistic domains or abstract concepts like Hermatic elements, these mental domains are basic mindsets which color the psion's ability.

Determining which Mental Domain a psion is in can be left up to the GM, or you can use the rules here. There are two traits which determine the Mental Domain of a psion: Distraction and Abstraction. If he has five or more total boxes filled in his Stun and Physical Condition Monitor, then the psion is Distracted, otherwise he is not. If he has used more Mental Attribute-linked skills in the past hour than other Active skills, then he is Abstracted, otherwise he is not.
If the psion is Distracted and not Abstracted, then he is in the Domain of Hate.
If the psion is Distracted and Abstracted, then he is in the Domain of Fear.
If the psion is not Distracted and not Abstracted, then he is in the Domain of Love.
If the psion is not Distracted but is Abstracted, then he is in the Domain of Rationality.
If a Mental Psion wishes to act as if he were in a different Mental Domain than the one he is currently in naturally, as an Exclusive Complex Action he can make a Willpower( test; for every two successes he can change one of his mental traits (eg: change Distracted to not-Distracted.) for up to ten Combat Turns.
Make sense so far?

Like the Hermatic elements, each Mental Domain corresponds to a school of spells:
Love: Health
Rationality: Detection
Hate: Combat
Fear: Illusion
There is no Domain for Manipulations; the Manipulation school is to psions what the Health school is to hermatics.
An interesting aspect of the psion's use of magic is how it is affected by background count. Because of the internal nature of a Mental Domain and how it interacts with a psion's spells, any effects of background count are halved (round down) when a psion is casting a spell from a school in his current Mental Domain (eg. a psion in the Hate domain only has a +2TN modifier to Drain Resistance when in a background count of 4). However, the modifiers are increased by one-half when the spell is in a different Mental Domain.
Psions can specialize in a particular mental domain as an aspected mage (as elementalists specialize in a single element), or as a full mage (as elemental mages do, receiving the same bonuses.)

According the Psionicist view, Conjured spirits are nothing less than pure thought given form, or, if you perfer, a mental process seperated from the mind. These "thought forms" work in the same way as spirits do, and the psion can have a maximum of (Int/2) thought forms active at any one time. Unlike normal spirits or elementals, thought forms seem to degrade over time: every hour after "Summoning" a thought form it loses one point of Force, until it finally disappears upon reaching zero Force.

Here's where I run out of ideas. What would be good stats and powers and such for different thought forms?

A smartlink, tons of cyber, and heavy artillery. OR just play a physad.

True, but no moreso than, say, Wujen.

The above seems like it might make playing psionicists interesting overall, but I have to take exception to this. You've gotta call it something else, because there's no way in hell love is actively physical or not distracted.
