new nether structure

i think there should be a new nether structure, that contains a boss, and contains chests with ancient debris, and very rarely netherite upgrades. other items as well, but those are the main ones. it could be made out of obsidian, or if that wouldn’t work, than any other block or maybe even a new one. inside this structure would be a new type of boss. maybe like an iron golem but more powerful and with more health. it could be called a thermal golem or something more creative. once killed, it could drop something called a thermal core. this thermal core can be combined with a blaze rod to make it into a new type of mace, like a thermal mace. this one could have a different effect. like instead of doing more damage with height, maybe you can pair it with an elytra and it can do more damage the higher speed you’re going horizontally. or, we could keep the height mechanic from the normal mace, but once you hit something a ring of fire spreads out and hits any other mobs too. those are just some of the ideas for the mechanic of the thermal mace but there could be better ones too. and a better name and design for the boss too.
