Solar Pillar

The Solar Pillar is one of the four Celestial Towers that appear during the Lunar Events. It is found in the orange/red moon area. Many of the enemies that spawn near it are melee-themed. After defeating the pillar, it drops around 30-40 Solar Fragments on average.

Tips
While fighting the Solar Pillar enemies, it is highly recommended to stay grounded. Airborne players are easy prey for Crawltipedes who do an excessive amount of damage.

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.

Trivia

 * This pillar was shown for a few seconds in the trailer for 1.3.
 * Just like the other pillars, you take no damage when touching the pillar melee.
