Reverse Magic

Epic Abjuration

  Casting Time: 1 reaction, which you take when you see a creature in range cast a spell
Range: 120 feet
Components: S
Duration: Instantaneous   You sabotage a target’s spellcasting by firing a disrupting blast while they attempt to weave their spell. The spell fails and has no effect, and the creature takes force damage equal to the spell’s level multiplied by 10. If the spell is a cantrip, the creature takes 5 damage and if the spell is Epic, the creature takes 100 damage.
If the spell affected by this spell deals damage, the type of the damage dealt by this spell changes from force to a type of damage that the affected spell could deal (chosen at random if that spell could deal multiple different types of damage).
