Question:
This rived monstrosity will rive you well if you canvass the trove
Answer:
Shattered Man or Fierce Shattered Man
Explanation:
This rived monstrosity - rived means broken, or shattered. *a small light clicks above your head* Shattered Man!
will rive you well - this guy will lay the smack down on ya! Level up or use PSI paralysis, cause' you're in for a tough battle!
if you canvass the trove - canvass means to inspect thoroughly. A trove is a find/treasure of some sort. Like the hieroglyph upstairs in the museum (where the Shattered Men are), or the Hawk Eye in the Scaraba Sphinx (where the Fierce Shattered Men are).
