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. It is the ranger-themed Tower.

During the battle the pillar will start with a large force field around it, which can be taken down by slaying 100 minions (150 in Expert Mode). Once the field is down, the pillar will become vulnerable, but minions will continue to spawn. The boss itself is fairly easy, having only 20000 HP and you take no damage when touching the pillar melee. While the boss may not be a threat, the minions it spawns deal high amounts of damage and can easily swarm the player if not taken care of.

Tips

 * A quick and effective way to kill all of the pillars is to use the North Pole directly and vertically above a pillar. Even if a player does not have any melee modifiers, if all of the snowflakes can make contact, the pillar should fall in less than 20 seconds.
 * Another strategy is to use the Nimbus Rod as you can leave the place and let it deal damage, placing 2 clouds, you just need to resummon it once, or even none at all.

Trivia

 * This pillar seems to had Ebonstone Block, like the others Celestial Towers.
