@MarkSparklFarkl Soul Knives make attack rolls like normal weapons but damage is 1d8 (no modifier) psychic damage? That is, indeed, what the Soul Knife feature says.

For you, a soul knife is a martial melee weapon
with the light and finesse properties. It deals 1d8
psychic damage on a hit,
That is incorrect they are finesse weapons so you would add the modifier on damage as per the finesse property.
