Hi i've got another question :

How i can display the owner trap in my chat ?

i try that but it doesn't work :'(
"{victim} didn't the trap of {owner}'s {killer} and die."

The {owner} placeholder is currently not available for traps, see https://umod.org/plugins/death-notes#available-variable-placeholders

Could you add it then?

The same for helicopter. I want it to display who shot down the heli with what but it will just say {killer} {attachments} etc.

But for traps it would be handy too so please add it
