Casting actor BP reference to Bind Event OnDestroyed

It is absolutely correct to listen for a character destroy event in the Level Blueprint, so I wouldn’t reccomend doing it inside your character BP.

Can’t promise to have the time to investigate the code you shared, but in the meantime:

Have you tried calling the Bind node as in my second screenshot?
Can you do the connection like that? If not,
what error pops up?(https://answers.unrealengine.com/storage/attachments/139055-screenshot_3.png)
