Fight in the floor

Heart Input!

He whispered into the enemy's mind: "You lose."

Immediately, the Armor reeled slightly and its entire body creaked with the sound of rusted metal, only for a second. Mark had used Heart Input on it and all its Mindpower had been consumed—-whereas Mark's own Mindpower was replenished by the Black Water in his World Space. 

The Armor stood still. It had been ready to face any kind of attack from Mark. Dream, heart, and even dungeon-type attacks, it was ready to face. 

It had predicted all kinds of attacks from Mark's side and had decided that Mark was no longer much of a threat to itself unless he used that weird power that he used on the savages some days ago to commit genocide. 

"This is not a heart, dream, or dungeon-type attack," it said coldly. "Your mutated bloodline gave you access to true mind-related powers, to the point that I made the mistake of gauging you with common sense."
