Nether Dragon and Armageddon dragon

the nether dragon should have 180 health and (if unarmored, normal difficulty) deal 12 damage to you by melee, have a fireball similar to the ghast, and be able to light blocks on fire. it should drop a nether dragon egg, which looks like the ender dragon one, but red with lava in cracks. when the nether dragon egg is placed next to the ender dragon egg on top of 2 netherite blocks with an end crystal on both sides, it summons the Armageddon dragon, which has 750 health, is immune to all potion / tipped arrow effects, deals 20 damage with melee (if in normal difficulty, no armor), and it burns the player, as well as launching the ender dragon's breath but with more blast radius and the effect lingers for a short bit after you exit and the nether dragon's fireball but with more blast radius and damage. when alive, it should make the sky turn red and occasionally summon endermen and blazes. when killed, it should drop a lot of XP and an Armageddon shard, which when held, causes the nether dragon to be ridable and you can make it attack. the Armageddon shard also looks really cool and can be used to decorate your base to show that you are a very skilled player. on death, the nether dragon has a 1% chance to drop a nether dragon head.
