Disruption

The power of the void washes over you, shielding you from one type of incoming spell damage. Starting at level 1, you roll 1d4 plus your spell casting modifier, and subtract that number from fire, thunder, lightning, force, necrotic, or radiant damage taken. Every 3 character levels above first level, add another 1d4 to the dice roll, maxing out at level 13, at 15th level,  the die type becomes a d6 rather than a d4. At 17th level, it becomes a d8. At 19th level, it becomes a d10. Should someone attempt to apply a magical condition, (such as sleep, petrify, curse, or charm as examples) you must roll a d20 constitution check against the level of the spell slot used, with the dc being 10 plus the spells casted level
