Sacrosanct
Legend
If someone were to tell me, "You have a power that you can use once per day where you can shoot an arrow and knock that dragon backwards 20ft and knock it prone." and I said "Oh, like a spell would." And they laugh at me? They're pretty clearly a jerk.lol look at the battlemaster fighter, my dude. I'm not gonna repurchase books from my least favorite edition of DnD to confirm, but I know from memory that forced movement and knocking prone, sometimes with size restrictions sometimes without, or with scaling size restrictions, was a thing in 3/.5e as well.
And regardless of this one very specific example, even if you weren't exaggerating the supposed singularity of said example, the vast majority of martial powers are literally just damage dealing attacks, with secondary damage riders based on martial principles like "cutting the target real deep in a vulnerable place" or forced movement based in equally martial principles like "hitting limbs or otherwise unbalancing the target with the strike, causing them to move against their will".
If you were to watch a tv show, cartoon, or movie, with those moves being used by characters described as the game describes them, and tried to call them "spells", literally anyone you talked to would laugh at you. Rightly. It's a completely, laughably, absurd position.
Again, it's literally called a "power", and it does supernatural effects. End stop.
