Here is an easy method that I used since I'm also no very good at the game. I'll make it short, sweet and to the point.
Team: Eyedol, Riptor, Rash
Eyedol
- guardian: Astral Tiki (gold)
- Artifacts: Myogene/Dragonskin Nanobots Mk(preferably level III), Mummy Talisman
- Consumable: Gibraltar Shield Mk III
Riptor
-Guardian: Fractured Ward (gold)
-Artifacts: Myogene/Dragonskin Nanobots Mk(preferably level III), Mummy Talisman, Demon Talisman
- Consumable: Embalmed Fingernail or Pickled Rodent Brain
Rash
-Guardian: Snake (blue or higher)
-Artifacts: Myogene/Dragonskin Nanobots Mk(preferably level III), Mummy Talisman, Demon Talisman
- Consumable: Embalmed Fingernail or Adrenaline Stim Beta Mk III
Note: Essentially I just spammed the grapple with Eyedol (Astral Tiki gives uninterrupted grabs) but make sure you look at how much time you have left with it because you will need to land a heavy attack to activate it again. (Also works well with Omens too).
Here is a video I recorded using my cheese method
