I'm trying to make a custom death message in my mod. I made my own DamageSource for this thing. However, I have one problem. The DamageSource requires a translation key and my mod is meaned to be runned on a server with vanilla clients. So is there any way to change the death message to a literal death message?

I've found it already. I can just override the getLocalizedDeathMessage method. This is what triggers the DamageSource class to send a translatable death message, and I can just return my own.
