Quantum Theory

You can do this only whenever Filena is around. On the bottom right of your screen you will see a blue circle. Hold whenever you are near Filena to throw her at an enemy and kill it, or tap for her to stun them. It takes a short while to recharge this move then you can use it again. Your Combo Throws count stacks in across multiple playthroughs. A good place to farm this is in the last chapter Scene 13. There will be unlimited Clones coming at you one at a time as long as you don't shoot the Core in the middle.
