the version of minecraft is 1.0 for the plugin: i want a plugin that when you do /fly a dragon spawns and you can fly with it, also the dragon spits fire on the other players and mobs and when they die they drop hundreds of diamond blocks with these diamond blocks you can craft a special op armor with enchantments of 6969 and when we right click with a sword that is crafted with those diamond blocks it throws fire and spawns a other dragon that we can jump into to make a baby dragon that poops bedrock used to craft a armor that makes us invincible wich can spawn a flying dragon named "beurette" that makes ghast noises if you do this you're a god
So it is very hard to find developers willing to write for it, as it is 10 years old, I sure won't be able to find something that can work with that.
That seems way too complicated for what i beleive could be easier in game using command blocks and spawn commands
