Curse magicks cascade off you to create a malignant aura with a 30-foot radius, weakening your enemies within it. Until the spell ends, the aura moves with you, centered on you. Whenever a creature hostile to you within the aura deals damage, it must roll a d4 and subtract the number rolled from the amount of damage it dealt.
