When a creature you can see within 30 feet of you makes an attack, you can use your reaction to roll one hemocraft die and subtract the number rolled from the creature’s attack roll. You can choose to use this feature after the creature’s roll, but before the DM determines whether the attack hits or misses. The creature is immune to this curse if it is immune to the blinded condition.
Amplify. You apply this curse to all the creature’s attack rolls until the end of the creature’s turn. You roll separately for each affected attack.
