How Aegis of the Hearth works

[loke]

@darkwing

The great many "utility items" with no penetration built in (like magic candle lighters, or chamber pots that destroy liquids inside) will function in a level 20 Aegis (minimum level for ritual) or a level 3 urban Divine aura but with a very negative penetration. If you go inside a stronger Aegis or a church with a stronger aura, they won't work. This means having a stronger Aegis gives more protection against items, but means if you buy in enchanted devices made outside the Aegis you will need to commission ones with stronger penetration.

When I don't immediately vote to accept your house rule, it is because I am deep-rootedly sceptical to all quick fixes to complex rules.

I really like the idea of weak items fizzling in strong opposed auras. For narrative effect, I'd probably prefer the light from your enchanted lantern to dim rather than go out, but the idea of auras having a MR towards opposing realms is good, I think.

(Or maybe the issue is with (charged) items' penetration)

[loke]

It may well be, but what do you suggest?

[ExarKun]

I suggested in our saga to ASG that it was to be reduced, for charged item, to 1 = 1.
It will reduce the "magi having 1 item with 100+ pén for those enemies they cannot beat using spells, but not having invested vis into talisman/invested/lesser item which are costly and destructible where a charged item destruction is just a non-event" (because in one season, my players create easily more than 10 charges and do only take 4-5 charges with them, for "bosses"' fight)

Also, in our saga, spells to target magi's worn items are common and often used before any other offensive spell. Against those, only a talisman is really effective (because parma); other items fall on the ground, broken. With charged item, the sheer number of them may mean that the spell destroy X charges (put in X items) but you wore more on you than the PeTe (or whatever, or with casting requiste if needed) spell targeted. And MR against those spells has been by consequence a must-have. Thief and cop.

Really? None of them are protected by Parma Magica? That would seem to disagree with

Magic resistance keeps magic away from the maga, her clothing, and other items that are very close to her.

Yeah, Parma covers most of the stuff you'd wear or have strapped to your body. A heavy pack or something large held in hand wouldn't be, but most everything else would.
