Aura of Despair

Blood Magic 7th-Level Spell
Casting Time: 1 action
Range: self (30ft Emanation)
Components: V, S, M (A vial containing the blood of a family member or trusted friend you killed. This cannot be substituted by a spellcasting focus)
Duration: Concentration, up to 1 minute
As you draw on the power of trusted blood betrayed, an aura of despair begins to spread from you in a 30ft emanation. The Aura fills all those within it with a general feeling of hopelessness and malaise, causing them to have disadvantage on all wisdom saving throws.
Upon first casting this spell, every creature in the aura must make a Wisdom saving throw. On a failed save a creature becomes prone and incapacitated, falling to its knees and weeping in despair. If a creature fails this save by 5 or more it takes [[4d12]] points of necrotic damage and its movement speed is set to 0 as it curls into a ball and begins weeping blood. A creature must also make this saving throw if it enters the aura during its turn or starts its turn there, though no more than once per round.
A creature may repeat this saving throw at the end of each of its turns, ending the effect on a success.

When you cast this spell for the first time, gain a mark of corruption.
