How do you capture a wizard?

[Emperor Tippy]

Or using one of the many spells, magic items, or class / racial abilities that give immunity to death effects. Life and Death replicates the Destruction spell, which is a death effect, iirc.

Now, that isn't to say such a god couldn't strip you of your immunity or find another way to kill you, but it would take slightly more effort on their part.

Technically it's not a Death effect, it simply works like Destruction but no where does it say that it picks up it's spell type.

Even if your DM doesn't agree, the deity can still just Wish you to a dead magic plane and then Life and Death you.
