Too much of a nerf, I'd say. Curse is nothing to laugh about. A horror mark, on the other hand is less severe in its everyday effects, but when the unit draws the short straw, it might very well be toast.

Then there is the problem of the Blood Thorn being a lifedrain weapon AND a path booster, which would make getting a horror mark from it decidedly unappealing when you want to boost ritual casting skills.
