U / Melkoth's Mystifying Miasma: The signature spell of the Grey Battle Wizard, this creates a numbing fog at medium range that attacks the combat abilities of the foe.
U / Steed of Shadows: Not to be confused with Shadowsteed, an insubstantial pegasus or drake appears under an ally within short range and carries them across the battlefield at incredible speeds.
Steed of Shadows for Evacuating a fallen Hero, to heal behind friendly lines. And Melkoth, for it is the signature spell of Grey Battle Wizards. Notably, while Smoke and Mirrors is categorized as a Lore Attribute in the Battle Books, something you don't cast, but that happens with each spell cast, these two are full Battle Spells. But!
Both of these can be cast with a single die, as they are the lowest at 5+ casting number. What does that mean? It means you can't get Tzeentch curse on you when trying to cast them with one die in the Battle Games. No miscast chance. You can still fail to cast them, but not miscast them. In the battle books.
In here? There is no safe battle magic. None. But... If you want to know about the safest Battle Magic, then it has to be these two. Melkoth's Mystifying Miasma is the signature spell of Grey Battle Wizards, and we have Warrior of Fog, Fog Bank arcane mark to train with. While Steed of Shadows may benefit from the same Warrior of Fog scouting/movment thing as well as our own Shadowsteed mastery. They are 5+ casts, next one up is 10+ and up.
These would be the two Battle Magic spells I might consider learning. One allows us to save a mortally wounded ally in the scrum from across the field, or deliver a champion to the enemy champion/casters for assassination, while the other is the signature spell of the order, and weakens enemies en-mass. And we have a trait to maybe help with it, and an arcane mark to help practice directing fog around. But Battle Magic is likely to be a long term goal, if at all, to be approached with the Gambler's blessing, and with prep time. If you do not respect it, and use it only in case of emergency, you will regret it.
EDIT: I think the only safe way to cast Battle Magic, is to invent one. And that is even less safe than learning a finished one. So it can be said you paid the cost of casting that Battle Magic when you lived through the process of inventing it. That is ridiculously dangerous thing to do. Invent Battle Magic, I mean. Again, a definite Gambler target in the distant future when we are out of AP hell.
