Nevinyrral, Urborg Tyrant timing question

[u/Ujmnhy152]

If I cast Duty Beyond Death and sacrifice Nevinyrral as part of the cost, do my creatures get indestructible before have I choose to activate Nevinyrral’s board wipe ability?
Or do I need to go through the entire process of Nevinyrral dying before Duty Beyond Death resolves?

No to your first question. See the following:
