Radiant Strike, Variant (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Components:||V, M (a weapon)|
You imbue your weapon with radiant energy, glowing with radiant flames and striking your foes with the power of your will or faith. Make melee spell attack. On a hit, you deal the weapons normal damage and you add your spellcasting modifier to the damage roll. If the creature is an undead or fiend, you add a 1d6 to the damage dealt and it has disdvantage in attack rolls against the caster until the end of his next turn, as radiant flames purify their flesh and bones.
This spell's damage increases to 1d6 (2d6) when you reach 5th level on top of the spellcasting modifier, 2d6 (3d6) at 11th level, and 3d6 (4d6) at 17th level.
