Alyssum's Investiture of Time

Until the spell ends, time is altered around you, and you gain the following benefits:

• You are resistant to force damage, your speed is doubled, and your AC includes your Intelligence modifier.
• The area in a 10-foot radius around you is slowed by time, causing attack rolls and saving throws to be made at disadvantage for creatures other than you. The radius moves with you.
• You can use your bonus action to create a 10-foot cube of aging time on a point you can see within 60 feet of you. Each creature in that area must make a Constitution saving throw. A creature takes 3d12 necrotic damage on a failed save, or half as much damage on a successful one. A creature that fails its save against this effect cannot use reactions until the start of your next turn.
