Hello there.
Here are a few unique kill effects ideas that could add some exciting and original visuals to the game :
Ethereal Glow 
: When a player kills another, a glowing light escapes from the killed player, like their soul rising into the sky, surrounded by a glowing mist.
Bubble Burst 
: When a player kills another, bubbles appear around the killed player, accompanied by the bubble sound from Minecraft (vanilla).
I know it's not great but hey, just in case anyone is interested
