@JeremyECrawford Does hitting an undead with Blackrazor resolve normally (i.e. do its damage) and then apply the Devour Soul feature, or does it do the Devour Soul feature instead of normally resolving the attack?

If Blackrazor deals damage to a creature, the Devour Soul property then triggers if the creature is reduced to 0 hit points. That's damage as normal, then soul chomping! #DnD https://t.co/A9eIpiOsDA

I was more interested in the last paragraph of Devour Soul's interaction which appears to trigger on each hit, but it sounds like you do damage and then the effects, due to the target being undead, kick in.

The last paragraph of Blackrazor's Devour Soul property causes the weapon to have a special effect when you hit an undead creature. That special effect doesn't replace the normal damage of the weapon. #DnD https://t.co/tRq5RWsdOq
