Ah. Concealing, not facilitating.
Well, less ambitious idea thrown in at the bottom of the post as an afterthought it is, then.
(For a less ambitious idea: 'A spell to cast on people, steeds, chariots, carriages, to make them leave no passage or trace.' Not sure what spell it would build off of though, whereas this one is "Add a carriage to Shadowsteed/Shadowrider? And make it conceal troop movement?". Also, I wanted a transport spell rather than a stealth spell, so I came up with the "Shadowsteed except a carriage" instead. Because I want a transport spell. And the recent mention of no hoofprints made me wonder "Wait, what if we tried to make a spell that actually left little to no passage? And which transported troops?")
We could probably make vehicles and squads of infantry more stealthy and hard to notice then.
I wonder what sorts of real-time battlefield mapping and fog-of-war-removing spells we can think up though? Being able to uncover troop movements in the middle of battle would be great, but the spells... All the ideas for that, that come to me, are along the lines of "Reveal or scry stuff" and Ulgu doesn't really have spells like that so -- but on the other hand, it's what the trait says, so...
It would be really great if we
could make some kind of spell to fight off the fog of war of a battlefield, but... It's a daunting process!
It feels like we've got a trait that would let us do wondrous things, things that our spellbook
doesn't usually have spells for, but in order to do them we'd have to come up with a spell
from scratch! And that's, again, daunting. But wonderful. It's both awe-inspiring and daunting!
... Maybe we'll get a trait focusing on the presence of "uncertainty and chance on a battlefield" or something too. (I'm reminded of a post that talked about how people saw chance and luck and uncertainty in history as it applied to warfare. And how it differs from the way we see chance in warfare now. So. Building on
that whole thing. Maybe something that brings that take towards war and/or magic?) Or some other spell trait. Maybe for logistics or movement.
Or maybe about revealing -- or obscuring -- things
other than just troop movements. That would be good. We uncovered Karak Vlag, we dispelled an illusion, we used a miscast to do it... ... Eh.
Nevermind, sorry. I drifted off into a whole 'nother direction here. Nevermind. It'd be cool if it happened, but, eh, who knows.
I guess when I'm excited or energized I babble a lot.
) against and army of Dwarven skaven and undead (it really isn't) while executing an ambush, riding atop her Shadowsteed, using information warfare, all to hold a narrow pass- does she have a martial of 73?
