Crawltipede

The Crawltipede is a strong, flying, worm-like enemy that spawns in Solar Pillar areas during the Lunar Events. Uniquely, it has no health bar, and instead can only be destroyed by damaging its tail, which can be difficult to hit. It seems more aggressive than normal worm enemies, and will fly directly at the player if they are airborne, dealing high damage until it is killed.

Crawltipedes primary role seems to be forcing the player to stay near the ground, opening them up to melee attacks from the other invasion enemies (such as Selenians, Drakomires, and Srollers). Unless you have sufficient firepower and accuracy to take down Crawltipedes before they make contact, they can be a severe threat to players who fight from the air.

Tips

 * The Crawltipede will approach flying players quickly and can deal massive damage. It moves swiftly and is able to make quick sharp turns, its mobility is far beyond any other worm-like creature. It is very hard to dodge even with high tier Wings. Because of this, it is recommended to defeat the Solar Pillar from the ground.
 * The Crawltipede will not target grounded players, but if it happens to spawn below you or be drawn down by another player, it can still do great damage if it happens to touch you.
 * Short jumps into the air are usually possible, but it's important to land again quickly. They immediately break off attacking when you touch the ground, but this doesn't mean they instantly get up and out of the way; it is still possible to run into them.
 * Having a homing weapon such as the Razorblade Typhoon or Chlorophyte Bullets will make fighting these much easier.
 * Fighting this monster as a gunner will prove to be difficult, considering ranged players use wings/boards/mounts for flying around most of the time and shooting enemies doing so, especially with the Hoverboard, considering it gives plenty of speed with its "left/right & down" movements.
 * Summoner Minions make short work of this enemy as they tend to target the tail.
 * Items that allow dashing will make this enemy substantially easier to evade.
 * To cope with the fast and accurate AI of the Crawltipede, the player can make it swirl around him/her, effectively dodging its attack. The UFO mount provides a good amount of mobility to do that.
 * It is a good idea to stay in the middle of the Crawltipede if it tries to spin, the player can attack it while avoiding its attacks.
 * Vampire Knives is a very good melee weapon against Crawltipedes, because of the amplified damage and health return ratio. Players can very swiftly restore lots of health and will find themselves hitting the two hearts capacity with just one or two successful attacks.
 * The Solar Eruption is an amazing weapon to defeat the Crawltipede, it's sweeping attack can easily hit the tail.
 * If using a decent magic weapon and Spectre Armor with the hood, hitting the tail can heal for 600+ hp, the highest self heal per hit in the game.

Trivia

 * The Crawltipede has the second-highest defense in the game, second only to the Dungeon Guardian.
