When a zombie drowns and transforms into a drowned, it always drops all of its random summoning armor. If the zombie were to be killed manually, it would always drop items it had picked up, but would use its random armor drop chances for natural spawn equipment.
Expected behavior would be for the dropping to match the death of the zombie – again, always drop loot that was picked up, randomly drop the rest.
Confirmed. I used
to test this with hand items as well, and it always drops both.
Another command I used to test this with armor was
In both cases, it dropped everything.
I hope that makes reproducing easier in the future.
