Accelerate Arcanum

You target a creature you can see within range, cutting the duration of spell effects on the creature in half. for example, if the target has mage armor (6hr remaining), and is frightened for 2 rounds; Mage armor now has 3 hrs remaining and frightened is reduced to 1 round. The target must make an Intelligence saving throw or take 1d6 force damage per spell affected. If casted on a friendly creature the caster can choose to make the saving throw themself and risk taking the force damage as Arcane feedback. Casting this spell at a higher spell slot increases the die rolled (1d8 at 5th, 1d10 at 6th)

Additionally at 6th level and above this spell instantly disrupts active concentration spells the target is casting or being targeted by.
