How would I make a certain trait?

[SlySlySly]

I want to make a trait for my civ leader that does:
if player's unit tech level is higher than enemy tech level
boost attack by 20%

How would I go about this?

I'm working on it but I'm completely lost. Can someone please step in.

I'm almost certain that if possible it will require LUA. I'm far less sure that it's possible at all. I can find no attack event in LUA, but then I only have a Civ V reference to LUA.

When I look into the civ 6 xml policies, if I cut bits and pieces, I can probably make it work.
