Is there a hook when npc stars/finishes attacking?

I’m in a need of a hook which would get called when an npc (non scripted) starts or finishes an attack. I didn’t find anything on the wiki.

So is there anything like that?

If there isn’t, how would i go around this problem?

As far as i know, this is not possible at the moment of this post.

Damn :frowning:
