Delayed Flash Glaciate

A bright icy blue streak flashes from you, then condenses at a chosen point within range as a glowing bead for the duration. When the spell ends, the bead explodes, and each creature in a 20-foot-radius Sphere centered on that point makes a Dexterity saving throw. A creature takes Cold damage equal to the total accumulated damage on a failed save or half as much damage on a successful one.

The spell’s base damage is 13d6, and the damage increases by 2d6 whenever your turn ends and the spell hasn’t ended.

If a creature touches the glowing bead before the spell ends, that creature makes a Dexterity saving throw. On a failed save, the spell ends, causing the bead to explode. On a successful save, the creature can throw the bead up to 40 feet. If the thrown bead enters a creature’s space or collides with a solid object, the spell ends, and the bead explodes.

When the bead explodes you flash freeze the area around each creature in a 20-foot-radius Sphere centered on that point makes a Dexterity saving throw and each target must succeed on a Dexterity saving throw or be affected by this spell for the duration.

An affected target’s Speed is halved, it takes a −2 penalty to AC and Dexterity saving throws, and it can’t take Reactions. On its turns, it can take either an action or a Bonus Action, not both, and it can make only one attack if it takes the Attack action. If it casts a spell with a Somatic component, there is a 25 percent chance the spell fails as a result of the target making the spell’s gestures too slowly.

Using a Higher-Level Spell Slot. The base damage increases by 1d6 for each spell slot level above 7.
