How would y'all rank the Trounce Domain Bosses (and Andrius) in terms of difficulty?

To refresh everyone's memory:

  • Stormterror Dvalin
  • Andrius
  • Childe/Tartaglia
  • Azdaha
  • La Signora
  • Raiden Shogun
  • Scaramouche
  • Guardian of Apep's Oasis
  • All-Devouring Narwhal
  • Arlecchino
  • Lord of Eroded Primal Fire

I'm just curious to see which bosses gave the most difficulty or which bosses have killed players the most.
