We really don't care for arguments today. Going about nearly nude when working is illogical. Unless you're a plain and simple whore working at whoring. Even then, if you're at all outside a warm building, you'll quickly catch hypothermia going about dressed in metal bands. Unless you try to godmod yourself out of any situation potentially involving direct combat (which we rather doubt you will), you'll eventually come into a situation where you're forced to fight prolonged.

Only being affected by iron isn't really logical, and it is very much overpowered. Not quite as OP as only gold, but still OP. We'd recommend going with metals instead. Perhaps refined metals being more effective against her than raw ore or contaminated ones. That'll make hiding a bit more challenge. We'd also suggest being able to take certain objects with you into the walls you're fond of hiding in. I.e. your peasant clothes. 

Or the opposite. Rawer materials are harder to pass through, metals are resistant. That would explain why she doesn't fall through floors / Stairs / the ground). 

The best way to hide being an evoker is by looking like everyone else, not by having dozens of potential relics on you. If someone wants to steal your relic, they will remove all objects they think could be it, not one at a time. And to be sure they do that, they would strip off any garments to be sure nothing is hidden underneath. And it is at that time the toe ring will become very suspicious. 

As the crossbow discussion was all done some 60-80 pages back, we're not in the mood for going through it again.
