Netherite armor doesn’t protect the player from any more damage than diamond does.

Steps to reproduce this behavior:

note: you will need 2 players for this.

1. Set the world difficulty to anything other than peaceful.
2. Using a diamond sword, kill a player wearing diamond armor while counting successful hits.
3. Using a netherite sword, kill a player wearing diamond armor while counting successful hits.
4. Using a diamond sword, kill a player wearing netherite armor while counting successful hits.
5. Using a netherite sword, kill a player wearing netherite armor while counting successful hits.
6. Compare the amount of hits between each test. They should be basically the same when the player isn’t regenerating.
