Spiritblind
-4 (-2 for physical adepts)
This character lacks astral perception, and can never gain it.

Interesting, and probably woth more than 4 points (6?) considering what this cuts the character out from (Centering, quickening, seeing invisible people, ETC). Would this affect a character's ability to astrally project?

I'm not sure about applying it to adepts though. Would this block-out their ability to use empathic-sens style powers too? It might be possible but seeing as they actually have to buy the power first (2 Power Points) I think they're gaining enough already by not buying it.

Interesting... But I'd put the points cost at 5 for mages in general.

If it rules out powers like Magic Sense and Empathy I'd put the cost at 2 for adepts, otherwise I'd just forbid it for them.

I'd also rule out that it is only perception that is affected - projection can be done normally. This just means that the mage lacks the fine control of keeping his astral body and his physical body aligned.

Dual Natured beings can, of course, not take the flaw. (unless they also have the blind flaw...make them blind on the astral too).

On second thought, since 5 points separate Full and Aspected mages, the cost for this flaw should really be 4 points. After all, for 5 points you give up projection as well as limit your magic in other ways.

i priced it as such because, combined with the Blind flaw, it equals the cost of the Blind flaw for a norm. physads don't get as many points for it because, of course, they can just not take astral perception at all, already.
