Poisonous Person

[Eldan]

Err, that's assuming you're playing the variety where you can't turn it off...

And from an apparently-D&D-centric perspective, as well.

For instance, let's say I'm playing Exalted, and for some reason, my Abyssal can't turn off his plague-powers. Chances are, said character will be indifferent, at best. After all, if he's a loyalist, he's already trying to destroy the world, and doesn't need the help of anyone living to do so, and if he's a renegade, then he's probably avoiding people anyway, so as not to inadverdently afflict them with his Resonance, and has appropriate Medicine Charms to keep everyone he does have to interact with perfectly hale.

True, but in pretty much any game I start, no mater the system, there will be a lot of talking. Having an aura that kills or infects things that come near to you (and yes, I'm assuming that it can't be switched off, otherwise, it's not much of a question) would bar you tons of social opportunities.

Yes, if you play someone omnicidal, it's perfect.
