Hi guys! For someone who looking for a 1-hit weapon, this is my 1-hit crossbow, hope it helps!
Yeah you see the cobalt crossbow. Cobalt has the fastest arrow speed. But at the beginning when you dont have enough modifier slots to upgrade draw speed, you need another material like slime, then replace it by cobalt later. The body and tough binding can be whatever you want (im using obsidian for reinforced 3 and slime tough binding is from reward bag) About modifier, you need ~590 redstone to get 0,25s draw speed (12 modifier slot). After that you can add anything (yeah after moss 3 and luck, i still have 1 slot, any suggest?)
About bolt, i used steel head (dam=manyullyn, ez to repair, less weight), bone rod, slime fleching. Add full quartz (6 slots full of quartz give max 167 dam, and i still have 4 slots remaining). Add diamond and emeral to increase weight. You can add moss to auto replenish too, but i think steel is cheap so it's better to add dam.
Tested, it 1-hited any mob in hard difficulty, took 2 hit to get wither to anti-arrow mode and he had only about 6-7% HP remaining, so i guess if i add more quartz or even smite, i can 1-hit him (maybe?)
That's all about my crossbow, if you have any question feel free to ask! And sorry for my bad English, i'm learning it ^^!
