A dog u can also get Iron and stone and dims from structure in the nether and overword
i’m giving you guys a challenge!
there is literally no point of trying for me, 1. i play bedrock, 2. i am 99.9999% sure that only pro players like dream can even have a shot of completing it and also, u would probably die in either the end fight, when ur fighting the wither, in the trail chamber for the mace, the actual 1000 DAYS, u probably will go to bastion for the gold for the netherite ingots and netherite upgrade and u might find a HUGE lava pool when mining/exploding for ancient debris
A mace?????? in a hardcore world??????
To craft a mace, (which is the only way to get it), you need a breeze rod and a heavy core. You need to find a trial chamber and survive the insane crazy amounts of armored mobs that spawn in it and collect a breeze rod dropped from a breeze. Next, you have to collect trial keys and find item spawners to get an ominous bottle from. After that, you need to drink an ominous bottle to make the spawners spawn even more dangerous mobs so the spawner will drop ominous trial keys. If you are still alive, than you need to find ominous item spawners and put an ominous trial key in. THERE IS A 1.5% CHANCE THAT YOU WILL GET A HEAVY CORE, THE OTHER INGREDIENT TO CRAFT A MACE. If there are no ominous item spawners left, you will have to find another trial chamber and repeat the entire process. THIS IS ONLY ONE OF THE CRAZY THINGS IN THIS CHALLENGE!!!!!!!

Oh yeah bedrock is supposed to be harder than java only for pros 😎 so u should play java because its easier to survive
