Related to last week's spell, this is a 4th level variant of Magic Missile with a bit of utility added.
Level: Magic user 4
Range: 10 ft/ caster level
Area of Effect: 1 creature or object
Components: V, S
Casting Time: 4 segments
Saving Throw: None
When this spell is completed a bolt of force leaps from the caster's hand to strike the designated target, never missing. The powerful attack causes 3 hit points of damage per level of the caster and strikes hard enough to throw a 1 lbs object 2 ft per caster level. Objects struck by Jonas' Jolt must save vs. crushing blow or be destroyed and stuck/locked doors may be forced open as if by a person with an 18/51 Strength. Any creature struck by Jonas' Jolt must save vs. paralysis or be knocked prone; small creatures save at -4, large at +4. If the Jolt strikes an object held by a creature that creature must save vs. paralysis at -4 or have the item knocked from their grasp.
A Brooch of Shielding takes 150% of normal charges to stop a Jonas' Jolt; to halt a Jolt inflicting 24 hit points of damage would take 36 charges from the brooch, for example. A Shield spells totally negates a Jonas' Jolt but the Shield spell ends immediately, its energies consumed.
