Hacking Kurapika's ability

Ok, I get it, if Kurapika removes the chain in his heart the multiplier will be removed, but hear me out, would this be allowed as per the known rules?

1) Encounter a new enemy

2) Swear to use my abilities only against this foe, piercing my heart with the judgment chain and swear on it.

3) Defeat the foe

4) Remove the chain from my heart

5) Encounter a new enemy and repeat the process

6) Profit
