Notes:
-You'll need freezing trap and CS for interrupts.
-Intimidation and Misdirection are good backups. (Misdirection for damage reduction on your pet)
-You must kill them roughly together. You can stun and trap the worm to stop his sonic casts after Tugar has fallen but it is quick and you will quickly get run over.
You'll need a mix and match of Prydaz, tenacity spec'd pet or Apex predator's Ring (IF you want to have a misdirection fall-back for cast), and Ideally some base leech (I was at 5%, using downgrade pieces to get it)
