I have done my research on MC advancements, and I have concluded that with the right setup, you can get 10 advancements with one arrow:

1. Voluntary exile
2. Take aim
3. Sniper duel
4. Bullseye
5. Ol’ Betsy
6. Two birds, one arrow
7. Who’s the pillager now?
8. Arbalistic
9. Uneasy alliance
10. Monster hunter

Just wanted to share this fact.

cool

I did it :D https://imgur.com/a/zrob2SY

oh wow thats a lot that share those requirements, pretty cool

no you cant as far as i can see. max piercing is piercing 4 which lets you shoot 5 mobs. for arbalistic you need to shoot 5 mobs of different types. for 2 birds 1 arrow you need to shoot 2 phantoms ergo you would need to shoot at least 6 obs with the same arrow which is impossible in vanilla survival.

arbalistic has to be all 5 at the same throw yes or yes? maybe you can do 4 before the important shot and get it all in that shot (even if it was setuped the advancement previously)

nice idea maybe this could be a speedrun category @KilleDragon yes you have to kill all 5 mobs with one arrow
