Bladesinger (5e Feat)
From D&D Wiki
As the elven warriors of old, you blend swordplay and spellcasting into a single deadly discipline. You gain the following benefits:
- You may use your Intelligence modifier in place of Dexterity modifier for attack and damage rolls made with natural, light or finesse weapons.
- You can use any one-handed melee weapon with the light or finesse property as a spellcasting focus, if you wield one.
- At 8th level and beyond, all one-handed melee weapons are considered to have the finesse property for you.
- You may use your bonus action to attack with a finesse or light weapon.
