Artery is -8 strength for 5 hours (in affects, so 6 ticks). Can cause bleeding.
Hurl torso is -6 strength for 5 hours. Always causes bleeding when it lands. This bleeding isn't stackable with impale.
Hurl throat is -5 strength for 5 hours and silence for 0.
I can't find actual logs of the other hurl locations, but they're generally something like -3 dex, -2 strength, or -3 strength, -2 dex, for 5 hours. Leg also lowers dodge skill, forearm lowers parry skill, and shoulder lowers damroll and bash skill.
Hamstring halves movement, then is -10 dex and increased movement speed for 6 hours. You can't hamstring again at all until it heals. Always causes bleeding when it lands.
Twist shoulder is -5 strength for 5 hours.
Twist leg halves movement, then is -5 dex for 5 hours.
Twist stomach can randomly give -5 strength or dex or cause bleeding for 5 hours. It's often just damage though.
Twist maledictions are stackable.
Bleeding on all these skills will generally wear off along with the malediction, but it can sometimes fade an hour or two before or after.
