Hitting them with 1 coin will cause all mist finer attacks to go to level 2, with another coin all mist finer attacks will go to level 3. HOWEVER, each mist finer attack has different properties
level one
P (high) - simply knock the enemy back
K (mid) - knock back
S (low) - trip/knock down
level two -
P - Will cause the enemy to bounce off the wall and back towards you, they can't tech for a very long time
K - Will cause the enemy to slide along the ground for a long time
S - Will cause the vacuum effect and the enemy will be pulled up and towards you
level three
P - Aims multiple attacks high and mid, the enemy then bounces up and falls nearby usually allowing for a combo as they cannot tech from these attacks
K - Aims attacks high, mid, and low. Similar properties to "P level 3" but it knocks you further back and is harder to follow up especially if this was thrown later in a combo
S - Aims attacks low then mid, finishes as a knockdown
most divine blade combos no longer work as the attack doesn't float the enemy anymore...yet substitute divine blade for Killer Joker and you'll get similar results to what you're looking for
