Blood Storm

The sky begins to weep spears of coagulated blood. At the start of each enemy turn, all enemies within 100 feet of the caster must make a DC 14 Dex saving throw with disadvantage unless they are flying, levitating, or under a ceiling or take 1d10 necrotic damage. All enemies hit by the spell also must make a DC 15 Con saving throw (DC 20 if cast as a level 9 spell) if they do not have Decaying. If failed, they gain Decaying until the end of that round. While Decaying, enemies take damage from healing effects instead of being healed.
