Unstable Fire Bolt

You hurl a bolt of fire at a creature or object within range. Make a ranged spell attack against the target. On a hit, the target takes 1d10 fire damage. On a crit the target takes 1d6 force damage in addition to the 1d10 fire damage. A flammable object hit by this spell ignites if it isn't being worn or carried. if the target blocks the Fire Bolt and the caster rolls a crit, the target also has to roll for a Dodge or a Dex check to avoid the 1d6 force.

If the spell is used against an object like a door, chest, cart, etc and the fire bolt misses, but the force still lands, it can take the door of it's hinges, blow open the chest, fling the cart, etc.

This spell's damage increases by 1d10 when you reach 5th level (2d10 2d6), 10th level (3d10 and 3d6), 15th level (4d10 and 4d6), and 20th level (5d10 and 5d6)
