I've been considering this for a while, and while I probably won't have a chance to play him as a character (blasted GM-ing duties), it is a fun concept to play around with. Also could make a good villain.

My basic idea is to make a character who is a specialist in Astral Security. With mages' ability to manifest while astrally projecting, it makes it much easier to leave the body behind.

The general concept is a paraplegic (wheelchair bound), very frail, character with extraordinary mental abilities. He also is skilled in close combat and has a weapon focus he brings with him on missions. As a mage, he's got a few mana based spells, but more importantly has big nasty banish & counterspelling foci. This combination makes him a good character for neutralizing astral threats.

The problem I run into is rationalizing poor physical stats with a high combat ability like bladed weapons. Also, no luck finding a good "paraplegic" negative trait. "Infirm" doesn't really cut it because of the doubled-cost for combat abilities.

Anyway, something I thought I'd throw out there and get other people's opinions.

Oh yeah, and hi again to people who remember me

While this character may make a good security mage, i'm not sure i'd want him on my team, sorry. At least in 4th. ed., manifesting isn't all that good.
As for the wheelchair-bound warrior, see the Oracle (ex-batgirl) comics. She pretty much kicks ass (hits ass?). Maybe he was once better physically, and after geing hurt he trained in using his arms (no kicks) in close combat.

Runners Companion p. 107.

Just to clarify Astral Combat is not a combat skill. It is a Magic Skill.

Does the weapon focus increase the astral-combat-skill also or just the approbriate skill for the weapon? (edged, blunt, etc.)?

Both

Cool.
