arcane time bomb

You manipulate the flow of time condensing it into a floating ball of energy or an object of your choice, every action you sacrifice to this spell will add 3d10 force damage to the total. Once you relies this spell's power it will emit a large amount of time energy ending the spell and dealing the force damage.  If the caster is knocked out this spell will become unstable affecting everything in a 500 feet radius of the caster.

at higher levels, if you cast this spell with a third or higher-level spell slot this spell will do 1d10 more damage
