Not, "no wiz" but "WIZ permanently =0"...

(This began with a meditation on, missing the old school kris knives.)

A character totally devoid of magic. We've seen the trope. General rules, or would it be so case by case...

I'm thinking everything from magical healing, to magical possession, to the ability to consciously use the magic in any item are non-starters. Same for magic items that affect the body. So, for example, a sword that was magically sharp would still get its benefit, but armor of dodging that worked by increasing one's DEX...

Could be a huge pain on the PC level, with GM adjudicatings and player grumblings, but zero-Wiz NPCs...

I suppose that a PC, upon rolling a natural '3' for an attribute, could be allowed by the GM to be rated "Null" instead. Completely immune to the warp and weft of Magic, but not unaffected by the results. I suppose that means that the PC could use any Magic Item that a Golem or other Unliving being could use, and be affected by any spell that generates a non-magical effect that could harm them (fire, ice, lightning etc) and of course no Healing. The PC could also be immune to any form of magical detection or scrying, making one a valuable Wizard Hunter...

This line of questioning makes me wonder-could a PC be viable with other 'Null' Abilities?

Null SPD=being carried everywhere, but able to use missle weapons and Spells, and take swipes at targets within arm's reach. Immune to paralysis/petrification/SPD curses.
Null ST=no Combat Adds for ST either positive or negative, unable to make ST saves, unable to use weaponry...a Land Jelly perhaps?
Null DX=no missle or melee weapons, no positive or negative Combat Adds, no Spells,no DX saves or dodging...mobile Wall of Flesh?
Null CN=dead meat, nonviable. Or, possibly immortal? Everything kills the PC(a blow, a glass of alcohol, a head cold) but roll 1D6 every hour, back to resentful 'life' on a 6?
Null IQ=Bestial intelligence, hunger, flocking instinct, fear etc. Can never make IQ tests or take IQ Talents, immune to Mind Control or IQ cursing...a lobotomized beast with a handler? Difficult to enjoy I think...
Null LK=no positive or negative Combat Adds, can't make LK saves, coincidences never happen to the PC, cannot have a Destiny or Fate, possibly cannot be Geased?
Null CH=will never have a say in things, will be ignored, might be hard to identify? No CH saves.

Hmmmmmm....

I like the idea of null.

Null CH would make a fascinating political campaign (be it game of whatevers, some form of democracy) where there's absolutely no persuasion, personality involved--just cold calculation into promises, past actions, threats, bribes, etc.
