Support adds NPC as effect

[Kater]

Hey guys, I have an NPC where I'm using this effect for the top pvp players.
But I found an NPC that is an effect, I would like to change it.

How can I change it, the command I use for this purpose is below.

I wanted to include an NPC because he has a very beautiful aura.

 

specialeffect 620,AREA, "Top 1 PvP#pvp_statue_1";
