Perhaps. I would expect the magus bringing it into combat to have some skill at doing so, otherwise they'd choose another option. Let's figure at least an Ability with specialty of 5 - not overly high. If it's enchanted, it's at least Superior if not Excellent (only needs to be +1), and if it's going to be a Talisman it will probably be Excellent. So let's figure we're at 8 now. 7 magnitudes of effects would be needed. That's a fair amount for a typical item, but for a Talisman you'd probably get to it pretty quickly since you get other bonuses while doing so.
Right and wrong. The duration can't be Momentary and lasting via vis. Just use a Constant duration, which isn't really limited.
True, it is probably correct that I will take other options before I try to amateurishly defend myself with weapon skill... At this early stage of character development at least.
Ah, ok. You meant instilling a constant MuHe effect not casting a spell. Constant is achieved with "twice a day triggered at sun rise and dawn", right?
Start with Aegis of Unbreakable Wood (HoH:S p.36). Drop it to R: Personal since you're enchanting the item. Now you have MuHe 10 for R: Personal, D: Sun, T: Individual. The staff is now "susceptible to fire, but is otherwise nearly indestructible." Add +1 for 2/day uses and +3 for environmental trigger to make it constant. So MuHe 14. If it's your Talisman, you get +5. Including Aura, Intelligence, and Magic Theory, you're probably up to at least 15, maybe significantly higher. Your Arts don't need to be that good to bump that up to 28 and pull this off in 1 season.
Well, as newly gauntleted magus that does not specialize in neither Herbam nor Muto... But anyway I'll keep that in mind and no longer hesitate to start with a (low score staff) weapon skill and atune a well made staff as talisman when I have the time and vis...
Once you start considering to use a talisman in combat, you should also look at
and on
Add one magnitude for a cubic foot of iron instead of a menhir, and make an iron staff or sword as light as a feather, or anyway as light as you like to fight with.
There is lots of time you can spend on your talisman that way. But you cannot carry a weapon around with you all the time - while you need to touch it to bestow your MR to it: otherwise it is very vulnerable to magic.
So you also might need to shrink/expand your staff by magic, if you wish to have it around everywhere. "Don't touch the iron toothpick of Pugnandi Peritus: he is very protective of it!"
Interesting Terram ideas, but I think I'll stick to Herbam because walnut wood has a nice bonus for Mentem magic, which is the primary focus of Prometheus ex Tytalus.
What do you think how Aegis of Unbreakable Wood and Hardness of Adamantine compare? Both state nearly unbreakable as effect. However the Herbam version is of lower magnitude, which sounds a bit suspicious - shouldn't it be easier to make iron unbreakable than wood?
Edit: I suppose there will be a Herbam way (potentially adding a Terram requisite), although this will be hard and take long due to missing skill in both Herbam and Terram...
I see, that your character is the one with the Personae.
In that case his talisman best be as inconspicuous as possible, or he might not be able to use it when venturing forth as a Persona. For a staff talisman shrinking would be nearly a must then - and Prometheus as Benessa can't just grow it back from a toothpick to hack about with it, unless he wishes to ruin her rep in an entire town or agricultural community.
An inconspicuous knife with a handle from walnut wood - or such - as a talisman might make the occasional life as a Persona a lot easier.
I thought that it might get along as a wandering staff most of the time and such would be unsuspicious for most personae I could develop in the future.
If that is a bad idea I don't know if the talisman should be a weapon at all.
I'd definitely add shrinking. Question was more if something like a staff (quite visible) conflicts with having multiple personae (not all of them carrying a huge weapon typically).
I was thinking about a crown made of walnut or something. On the other hand one can seldom wear it without triggering suspicion either. Maybe a wooden mask made of walnut wood...
That is for growing the staff from toothpick, not for wielding a staff as Benessa in general, or is it?
You miss the context of this recommendation: if you make a staff from iron to give it Hardness of Adamantine, its weight is a multiple of a normal quarterstaff or Bo, so you need a way to significantly reduce it.
On the whole burning thing, I figure it's still wood and wood burns. It's just stronger. Otherwise these and Doublet of Impenetrable Silk in the core book are essentially all doing the same thing. In that last case, you still want your doublet to be flexible, different than flammable, but the same sort of idea.
No, I didn't miss the context. The statement itself mostly missed that context and is now being changed. Retroactively changing a statement doesn't make comments about how it used to be in error. Only a quarter of the original comment might have even possibly fit that context and the new changes. Making an iron staff as light as a feather doesn't. Making a sword as light as a feather doesn't. Making a sword "as light as you like" doesn't. Making the iron staff "as light as you like" might. The new statement about needing to reduce the weight of something that is too heavy is a good one.
It is just not new, but already implied in the context of my original post: it is the reason, why The Weightless Menhir got into it.
Making a sword/staff as light as a feather with The Weightless Menhir is possible, so I mentioned it - useful or not. Making a sword "as light as you like" without otherwise changing the properties of its blade is very useful, though: bladesmiths worked on it for the centuries following the 13th, before coming out with schiavone and rapiers.
