Craft the weapon
On the crafting table, place a heavy cannonball over the vortex core. The core is obtained from the Vortex, the heavy core is obtained from ominous vault trial chambers. A regular key does not open this vault. Reference: Java 1.21: mace.
Do not confuse the rod and the wind charge: one rod produces 4 charges, but the mace itself requires a non-recycled rod.
First hit from three blocks
Our training stand is a ledge of 3 block above a wide, flat area, without lava and void. Start with full health and no Gust to prevent a successful hit from triggering another unexpected jump.
Wait for the target near the base, step down and hit while falling. An early hit immediately after a jump may not satisfy the height requirement; too late and will end in landing before hitting. Several repetitions from a low ledge are more useful than the first jump from a tower.
The difference between keys and tests is discussed here: Trial chambers: your first rooms in Java 1.21.
Choose an enchantment for the task
Density increases the dependence of damage on height, Penetration reduces the effect of armor. In regular Java they are incompatible with each other and with some damage enchantments; Don't assemble the book without checking the final clue.
A gust of wind throws you up after a crushing blow. Wind Charge is a separate consumable item for the initial boost. First master it on the ground without an enemy: near the edge, horizontal movement is dangerous even with good armor.
