Your touch thins the blood of your target, causing it to spill with unnatural ease.
For the duration of the spell, the subject bleeds profusely through any open wound. Each new hit from a piercing or slashing weapon or effect that deals damage to the subject also deals 1 point of Constitution damage. This ability damage is not multiplied on a critical hit.
Because this spell thins the subject's blood, repeated uses cause additional difficulty. In addition to the extra damage, a target subjected to a second use of this spell before the first has expired also takes a -4 penalty on Fortitude saves against disease, poison, or the sickened and nauseated conditions.
