Is this a bug? Sure, with the name "Terror Larva" it might actually be intended, but as a Fire Mage you're telling me I cannot use my Living Bomb, Phoenix's Flames or Blast Wave while questing. Plus is it possible an Ignite could spread to them anyway?
Here's another larva that's neutral, not aggroed, and it has 27 billion health.

Found another one, but I sheeped it, so it's now a Sheep with 156 billion health
