Boney wasn't saying the Ambers have nothing meaningful to contribute, only that they can't solo the project. They have at least some understanding of waystones from the guy who got us the dragon obelisk, and for ranging through the wilderness where waystones tend to be, there's no one better. I think the Hag Witches are a good contribution to the waystone project but I think the Ambers could be even better. Just, you know, we won't auto-complete the project by grabbing the nearest available shaman.
Edit: My response got deleted somehow. It boils down to me not putting much trust in the Ambers having anything equivalent to the Jades or Lights and that they likely just have the highest concentration of Wizards who know where all the Waystones are and have experience dealing with their maintenance and rescue within the paradigm of Teclis and the Colleges.
I am not against recruiting them. I am also not for it. If a plan has everything else I want I'll vote for it regardless of Amber inclusion.
If you want that, we have substance of shadow on a normal sword. Given that a shadow sword that passes through armor wouldn't be able to parry anything, increasing the size seems like making it less ulgu-friendly for entirely aesthetic reasons.
Seriously, if people WANT to practice branarlhune in a sparring setting, we CAN'T use lethal spells for that: it defeats the entire purpose of sparring to murder our partners.
I was thinking less of a sparring blade and more of a Branulhune light that allows a fighter to actually apply Branarhune techniques practically and lethally, whether they are waiting to inherit our sword eventually or otherwise.
You're right that there's things a summoned Shadow Dagger style greatsword could not do that a Greatsword with Substance of Shadows could (parry and have weight). But the inverse is also true. Your suggestion can't work in light and daytime environments, can't deal seriously disproportional damage and if you materialize it as it swings through someone's body, which you have to to hurt them (especially through armor) then your blade is stuck inside of the target if you're lucky or has scary explosive effects if you're unlucky.
A greatsword (especially if weightless and summonable) has a serious advantage over a dagger. Range and reach. It's like a lightsaber. You can't kill someone a meter away and continue swinging towards the next target with a Shadow Dagger. You can't bisect someone with a torso the size of a tree trunk with a Shadow Dagger. You can't fight in an active battle like Mathilde would with a Shadow Dagger.
I'm still pretty curious what trait people are intending to use to make an ulgu sword spell possible.
What about ulgu aligns with swords?
The ancient myth about Ulgu
being a sword for one. The large plane that cuts and separates. The part where a dagger is just a small sword. The relationship between Ulgu and the Sword of Gazul, with which he (is conceptualized to have) separated the Glittering Realm from the Warp, reinforced by the creator of this spell we are trying to create when she used the Ulgu-Gazul connection to send half a million souls into the Aethyr (the realm of concepts and magic).
You want me to come up with more? Because I'm sure I already have exceeded the amount of connective concepts used to make a whole horse that rides as fast as the dusk/dawn or looking as scary as the face of Death or choking them with "shadow" tendrils.
Agreed. Once we've finished the invention of Branarhune as a sword style I might like to look into the possibility of an Ulgu spell based upon it.
But that's really a matter of chickens and unhatched eggs. Depending as it does on the (in my mind plausible) but far from certain results of grandmastery having at least some applicability to spells.
This on the other hand is a fair argument IMO. I'm not married to codifying this (or any) spell right this turn.
I mean yes, my point was that they are precursors culturally, but the lack of any trace of their magic in our lore would indicate a magical compatibility. The other option is that they were magically compatible, but a bitter cabal of traditionalists decided to take those magics to their grave rather than sharing them. It does not seem reasonable that there would be that much loss of lore for purely political reasons
Maybe the answer is much simpler. Maybe Ulgu Arcane Marks prevent the use of most or all useful Hedge Magic. So the first recruits could cast both, until they couldn't. And then they gradually stopped teaching Hedge Magic to new recruits because what's the point when getting at least one Arcane Mark is considered very normal for anyone who makes Magister.
