The ender dragon's unique launch effect is not mitigated by netherite armor.
Steps to reproduce:
If necessary, use the
/spawnpointcommand.Enable the keepInventory gamerule:
/gamerule keepInventory true/gamerule keepInventory trueRun the following command to summon the ender dragon:
/summon ender_dragon ~ ~ ~/summon ender_dragon ~ ~ ~Run the following command to keep the ender dragon in place:
/setblock ~ ~ ~ minecraft:repeating_command_block[conditional=false,facing=up]{Command:"tp @e[type=minecraft:ender_dragon] ~ ~ ~",auto:1b}/setblock ~ ~ ~ minecraft:repeating_command_block[conditional=false,facing=up]{Command:"tp @e[type=minecraft:ender_dragon] ~ ~ ~",auto:1b}In the center of the ender dragon, go into survival mode, then move into its face. Notice how far you'll get launched.
Go into creative mode and equip netherite armor.
Repeat step 5, noticing that netherite armor does almost nothing to mitigate the ender dragon's launch effect.
Can confirm in 23w51b, though this may be considered a change request.
