depends in the version. and stage of game
What's your MC loadout (Weapons and armor)?

Full netherite armor, sword, bow, trident, healing potion, harming potion, water bucket, lava bucket

Full netherite with All the enchants possible, prot 4 and then the rest of the enchants. Netherite sword with sharp 5 and the rest of the enchants. bow and crossbow with all enchants. Crossbow must have piercing. Trident with riptide and the rest of the enchants. water bucket, maybe lava bucket, and a stack of e-pearls. a stack of gaps, and if I get it, a god apple just in case.

Imagine using armor
Ngl one time i forgot to put armor so i died in a raid
Sad
what do yuo mean, I killed the dragon with no armor and no weapons because I was so mad and also was sad.

Full Netherite, Unbreaking, protection, thorns, and mending on all armor. Swift-sneak, Respiration, Depth Strider, on armor as well.
Sharpness Netherite Sword + Fire Aspect + Knockback + Mending + Unbreaking.
Sharpness Netherite Axe + Efficiency + Mending + Unbreaking.
Speed + Strength + Poison Potions.
Gold Apples. (God if possible.)
Shield + Unbreaking + Mending.
Bow + instant damage 2 arrows. Unbreaking + Power 5 + Mending + Flame + Punch.
Crossbow + fireworks. Quickdraw + miltishot + Unbreaking.
Flint and Steel. Unbreaking + Mending.
Fishing Rod. Unbreaking + Mending.
I personally use this in Java:
Full netherite - Blast protection III on all, Swiftsneak II on leggings, and Thorns II on all.
I use a netherite axe, mending and durability (or something idk).
Oh, and crossbow, I usually use fireworks to make it harder for enemies to see and it hurts them from a explosion, unless its mobs.
NOTE: Java or Bedrock, say this in the comment, the version must be the current version of MC
