This WA comes in handy when you forget to CC the pesky little Scalebinders and they put down the annoying fish stick.
Once a fish stick is up a border glow will appear on its nameplate so it's easier to tell them apart.
There will also be a splash sound for extra alert if you happen space out and don't register the nameplates.
The sound can be turned off at any given time if it annoys you.
The gif has scavengers on it because the NPC ID was changed for preview purposes.
