Phase 2 Ender Dragon

Hello minecraft. How are you doing? I have a good idea. When the ender dragon gets defeated,a phase 2 should start, which will be significantly harder than the other one. This phase two would be optional ,but would drop much better loot,like diamonds, armor ,a mace or even netherite! It would be a slight red colour and would spawn two more crystals. It would also drop a poisonous breath,like the original one,but much more deadly.From it you would make a new Armour with more protection.The rest of the fight would be the same. Please take my suggestion into account. If not,still have a nice day!
