The Giant Worm is an Undergroundenemy that tunnels through blocks to attack the player, spawning in the Underground and Cavern layers. It makes a distinctive shuffling sound that grows louder and more rapid as it approaches the player, providing an indicator of its presence and proximity. It also leaves behind a subtle particle effect in its trail.
The Giant Worm's body and tail do the least damage of all current Enemies, but due to its large size, it is capable of striking a player multiple times in a single pass.
Spears are the quickest way to deal with Giant Worms early in the game, along with any other weapon that can deal multiple hits at a time.
Using a Flaming Arrow against the Worm will set it on fire, making it easier to track.
If the player has a Slime Gun and hits the Worm, it can also be tracked more easily due to the slime effect left by the debuff.
Giant Worms can surprise new players due to being able to spawn even when the player is slightly above Underground.
Trivia[]
The Bestiary entry for the Giant Worm: "These itty bitty diggy dawgs dig through the earth and take focused spelunkers by surprise, causing unwanted distress."
All segments now share a life counter, instead of individual life counters for all segments. Previously Head, Body and Tail had 10, 15 and 20 health, respectively.
