Disruptive Bolt
3rd level evocation (Wizard)
Casting Time: 1 action
Range: 90 feet
Components: V, S, M (a tiny glass marble)
Duration: Instantaneous
You fire a mote of disruptive arcane energy at a creature or object within range. The creature must make a Dexterity saving throw. A creature takes 8d4 force damage on a failed save, or half as much damage on a successful one. If the creature struck by this bolt is concentrating on a spell, the damage done by this spell is not halved when calculating the DC for the creature's concentration check.
For example: If a creature suffers 20 damage from this spell, the DC for its concentration check is 20 instead of 10.
At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the damage increases by 1d4 for each slot level
