The next time you hit a creature with a weapon attack (normally a melee weapon attack), do so before the spell ends. The normal 5e weapon would glow with astral radiation like you strike.
Branding Smite spell 5e deals extra 2d6 radiation damage to the target. This makes it visible whenever it’s invisible.
When you cast this spell, make sure to use the spell slot that is 3rd level or greater. Also, the additional damage will be increased by 1d6 for every slot that is above the 2nd.
