Smiting Warrior (5e Feat)
From D&D Wiki
Prerequisites: Proficiency with at least one martial melee weapon
You have learned how to imbue your weapon attacks with magic to make them much more powerful. Choose two of the following spells: searing smite, thunderous smite, or wrathful smite. You can cast each of these spells once using this feature, and you regain the ability to do so after you finish a long rest. If you are of 8th level or higher, you also gain the ability to cast branding smite once using this feature, and you regain the ability to do so after finishing a long rest. Charisma is your spellcasting ability for these spells.
