Siege Wurm

Description
Siege Wurms are a special type of Sand Wurm that fires a powerful explosive ranged attack called Wurm Siege. Unlike Sand Wurms, Siege Wurms are stationary once they have surfaced and will not follow players. Like Sand Wurms, they are heavily armored and take a long time to take down. Their sole damaging attack (Wurm Siege) takes three seconds to cast. Interrupt it, and the battle becomes a mere matter of whittling away the creature's health.
