Effect to die mob

[ohyono]

Hello.

 

Well, is not great looking and what is quite specific. What I want is that the mobs die break. That would accomplish the effect 135. I try a script using the command OnNPCKillEvent, but'll look like the target disappears before you apply the command, so the only solution I can think of is via src. 

 

I hope can help me, thank you very much anyway. 

 

P. D. Sorry for bad English
