Can it be done in minecraft that the end dragon does not harm a block? I installed the plugins worldquard and worldedit
You can easily do that via Gamerule → / Gamerule DoMobGriefing false
I hope I get the command. I wrote correctly.
However, you should keep in mind that zombies will no longer be able to enter doors afterwards, Endermen will no longer be able to lift blocks, and Griefers will not be able to blow up blocks.
If you think the ender dragon should no longer destroy blocks, you must / gamerule mobGriefing false.
