Wurm

Wurms are giant worm-like creatures that burrow through the ground. Some wurms are able to use extended ranged "siege" attacks. They are generally larger, more aggressive versions of worms. The larvae state even resembles worms.

Notes

• Junundu are also wurms.
• Wurms all have increased armor, immunity to knock down, and most have an equal amount of armor against all damage types, despite being Warriors or Rangers.

Trivia

The Guild Wars 2 Wiki also has an article on Wurm.

• Wurm, which means 'snake' or 'serpent' is also another archaic name used for Dragons.
