Law managed to get a hit in Doflamingo, but his attacks did not end there.
A part of the castle was sliced off inside his ROOM, and thrown at Dofla an Trebol.
Doflamingo uses a Spider Nest move to block the huge object, but Law uses Tact to hurl loose rubble at Doflamingo.
Dofla easily dodges them, and Law teleports behind him with Shambles to attack him with Scalpel.
Dofla blocks the move and tells him to stop endlessly hitting him with worthless moves.
He is disappointed that Law has turned into a emotional hothead.
If Law really wished Dofla's death, he should have stuck to the plan to pit Kaidou against him.
At the moment Law chose his emotion for Corazon, his death was decided.
The note Corazon was trying to hand to the marines would have saved Dressrosa. The tragedies in this country may never have happened if Law hadn't failed that day.
But Law doesn't think that's Dofla's true feelings. Dofla tells him he's wise, indeed regardless of what the note said, he would have changed his plans and taken the throne anyways. Everything Corazon did was a waste!
Law tells him no, everything I do until my last breath, credit goes to Corazon!
Doflamingo agrees... yes, what actually transpired is the only reality.
The fact you ate the Ope Ope and fled, the fact you are here fighting me.
Dofla then puts his foot over Law's arm, and slams him down into the ground.
Law's arm is sawed off by Dofla's Fretsaw.
