Time for the last Eldritch Knight spell for a bit-the Weapon Halo!

 

Weapon Halo
4th-level evocation
Casting Time: 1 action
Range: Personal
Components: V, S, M (a weapon)
Duration: Concentration, up to 1 minute

When you cast this spell and touch a melee weapon, you are instantly surrounded by fiery and icy floating versions of the weapon.  For the duration of this spell, any creature that attempts to attack you with a melee attack has disadvantage and takes 2d6 cold and 2d6 fire damage.  The creature that succeeds at a Constitution saving throw  reduces the damage by half for each type of damage.

I’m working my way up from level 1 to 4 for the Eldritch Knight, so today will be level 3 and the Force Backswing!

 

Force Backswing
3rd-level evocation
Casting Time: 1 bonus action
Range: touch
Components: V, S, M (a weapon)
Duration: 1 minute

When you cast this spell and touch up to two melee weapons, these weapons take on a ghostly aura as force echos of the movement follow them wherever they move.  For the duration of this spell, any creature you strike with a weapon under the effect of this spell takes an additional 3d6 force damage as the echos rip through the target.

How about we continue the spells for DnD 5e and the Eldritch Knight?

 

Let’s keep building on the them of the Eldritch Knight.  How about some weapon based spells for above 0-level?

 

Lighting Rod
2nd-level evocation
Casting Time: 1 action
Range: 30 feet or touch
Components: V, S, M (a weapon)
Duration: instantaneous

Choose a target in range, and either make a melee spell attack roll or a ranged spell attack roll.  On a hit, the target takes damage equal to the weapon’s damage  plus your spellcasting ability modifier as you throw or strike the target with the weapon.  Next, the creature must make a Dexterity saving throw.  On a failure, lightning shoots from the sky and does target takes 4d6 lightning damage.  On a success, the spell fails, but the spell slot is not used.  In either case, the weapon returns to your hand.

I’ve been designing spells for something secret and reading the Sword Coast Adventurers Guide.  Let’s combine those two.

 

Sonic Shove

Evocation cantrip

Casting Time: 1 action

Range: 5 feet

Components: V, M (a weapon)

Duration: Instantaneous

As part of this action used to cast this spell, you must make a melee attack with a weapon against one creature within the spell’s range, otherwise the spell fails.  On a hit the target suffers the attack’s normal effects, and a sonic boom infuses the area.  That creature must make both a Strength and Constitution saving throw.  If it fails the Strength saving throw, the creature is moved 5 feet away, knocked prone, and you are no longer considered engaged if the creature does not have reach to attack you with one of its melee weapons.  If it fails the Constitution saving throw, the creature is dealt an extra 1d4 thunder damage.

This spell’s damage and thrown distance increases when you reach higher levels.  At 5th level, the spell’s thunder damage increases to 2d4 and the thrown distances increases to 10 feet.  The distance increases to 15 feet and 3d4 thunder at 11th level, and to 20 feet and 4d4 thunder at 17th level.
