How to get Arbalistic

Enchant a crossbow with Piercing IV so the arrow passes through up to five mobs.
Build a tight pen and gather five different mob types in it. Leads, boats and name tags keep them in place; armor stands and mannequins also count as targets.
Weaken every mob to one hit: punch or use a weak sword until each would die to a single arrow.
Fire one arrow through all five so each dies to that same shot. The challenge is hidden and pays 85 XP.

Tips

An easy lineup: chicken, sheep, pig, cow and one zombie in a 1-wide corridor. Fire at eye height of the tallest mob so the arrow travels through the whole row. It is a hidden advancement, so it only appears in the menu after you complete it.
