I'm having trouble with screenshots, but I just loaded a game to check this. I'm currently in the Beast of Winter section of the game, fighting Shambling souls. Xoti grazed one with this spell for 6 damage. Checking the full damage calculation, I see that the initial roll was 18.4, reduced by 50% for a graze, increased a bit by might and items, then reduced another 50% for Veil touched.
Getting a damage roll of 18.4 on an ability where the minimum is supposed to be 124 feels like there's something wrong to me.
