Depends which chase do u have on main+pet? Sasuke n Karin has 3 Chase Hinata 2. Find chase that are related to each other.

just ex: lets begin from my team.
Tobi : Chase and attack Knockdown cause low float
Zabuza : Chase and attack low floated cause repulse
Asuma : Chase and attack repulsed cause knockdown
Main : Chase and attack Knocked down cause High float

If Tobi attacks 1st with these Chase at least u have 5 combo. If chase doesnt continue previous chase, they will be stopped.
for exm:
Tobi : Chase and attack Knockdown cause low float
Kankuro : Chase and attack Knocked down cause low float
Asuma : Chase and attack repulsed cause knockdown
Main : Chase and attack Knocked down cause High float

If Tobi attacks 1st, u only have 2 combo. Because there is no chase continuing previous chase from Tobi.

Just example mate. U can have Knock down on Pet right?
