Ideas of questionable quality

[warcrimes]

if a wizard touches (ie. deliberately picks up) a gun they should lose all of their magic powers. it's one or the other magic boy

thats a solid idea and has basis in a lot of fantasy lore. 
the other way this can go is if they try to fire a gun, they have a 50% ( or greater) chance of it blowing up and knocking an arm off. 
personally leaning toward the latter, but either way works.

Use of any technology by a wizard should end with things either blowing up, or harming the wizard.

Granted this now makes it harder for wizard to give themselves captain level access outside of just stealing caps ID or bribing the hop with a meth golem.

On a side note, perhaps wizard should be able to command golems like pets. e.g "Sit, sic em, guard" etc. Petting golems is ill advised.

I think a fairly low-ish chance of blowing out electricals would be sufficient for most things, like how lightbulbs blow from heat. Just have maybe 10% chance of blowing out any appliance he uses, but significantly higher for weapons.
