Tailbone Short Sword - When performed, the user raises the weapon in the air with two hands, creating a wind-like aura that envelopes the sword. The user then smashes the weapon to the ground, releasing a quake attack that damages any enemy directly in front of the user. When an enemy is hit by the attack, it will be knocked down to the left or right depending on how the attack traveled.
Tailbone Spear - When performed, the user brings back the weapon, creating a wind-like aura that envelopes the spear. The user then thrusts the weapon, releasing a blast of air that damages any enemy that is in front of the user. If this attack connects, the enemy will be knocked down directly in the path of the attack. The attack is able to go through structures.
This skill is good for clearing up mobs of enemies, as it will connect with most of them. Take note that large enemies, such as Gertrude's Knights, will not be knocked down but instead staggered in five consecutive hits. You can use that to your advantage by using the dagger variation, as it will deal multiple hits to any enemy that does not get knocked downed.
This skill is effective against players who roll directly into you, as the attack lingers for a brief moment. You can also catch them off guard with its long range. If a situation occurs where you are near a ledge, you could knock players off with relative ease.
