Vortex Pillar

The Vortex Pillar is one of the four Celestial Towers. It appears during the Lunar Events. It is found in the green moon area. After defeating the tower, it drops around 30-40 Vortex Fragments on average.

Tips
A quick effective way to kill all of the pillars is to use the North Pole directly and vertically above a pillar. Even if a player is not a melee build, if all of the snowflakes can make contact, the pillar should fall in less than 20 seconds.
