Post Inkmatas bossfights.
The Limitless Devourer's arena would be in the Citadel. The Limitless Devourer would probably be the most annoying/difficult bossfight because of it's high defense and it's ability to do anything it wants to the player. The Limitless Devourer would be able to one-shot the player in a specific attack and has lines it can say
The lines it can say
At full health
"Is that all"
"You are weak"
"You defeated your own family members but you can't beat me, how weak"
"You are futile"
At 75% health
"Now we are getting pumped up!"
"Let's shift things up"
"Parry this you f**king casual"

At 50% health
*Roars* "YOU ARE AN ANNOYANCE"
"I CAN END YOU SO EASILY"
"QUIT FOOLING AROUND"
"My turn"
At 25% health
"DON'T GET COCKY, KID!"
"PIECE OF SHIT!"
"I CAN SEE YOU ARE SOMETHING"
"DIE ALREADY"
At 5% or lower
"Is this really my end!?!"
"A GOD DOESN'T FEAR DEATH"
"No..."
"I... have... been... defeated"
The Limitless Devourer usually drops 100-200 Limitless Scales and 50-100 Cosmic bars
The Limitless Devourer Attacks are completely random making memorizing attack patterns useless.
