Your melding of swordplay and arcana grants you the following benefits.
Martial Cantrips
You learn the Force Buckler cantrip and one of the following cantrips of your choice: Arc Blade, Burning Blade, Frigid Blade, or True Strike.
Manifest Weapon
As a Bonus Action, you can create a Simple or Martial Melee weapon made of magical force in your hand. This weapon counts as being worth 1 GP for the purposes of Material components. You can use this weapon as a Spellcasting Focus.
Whenever you attack with the manifested weapon, you can use your Intelligence modifier for the attack and damage rolls instead of using Strength or Dexterity. The weapon deals Force damage or its normal damage type.
The weapon vanishes at the end of your turn if you aren't holding it.
