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. Instead, its weak spot is its tail, which can be difficult to hit. However if you manage to hit it you do 10 times more damage than you normally would against an enemy. 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.

Tips

 * The Crawltipede only targets airborne players (does massive damage) and is hardly avoidable even with good wings. Because of this, it's recommended to defeat the solar pillar from the ground.
 * The Crawltipede is completely harmless towards grounded players.
 * Short jumps into the air are usually possible, but it's important to land again quickly as they immediately break off attacking when you touch the ground.
 * The Crawltipede can go about as fast as you can, so if it touches you, it'll probably at least severely damage you.
 * 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/whatever for flying around most of the time and shooting enemies doing so, especially with the Hoverboard, considering it gives plenty of speed with it's "left/right & down" movements.
 * Summoner Minions make short work of this enemy as they tend to target the tail.
 * Items that allow dashing make these 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 it's attacks
 * Vampire Knives are a good weapon to use against the Crawltipede, because they have a wide range and can hit its weak point easily while also collecting health.

Trivia

 * 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.
