Seems like the error had to do with the initialization of the function which was coded with the diamond attack. I moved this function to the starting relic which should fix the issue. The reason I wasn't seeing it was because I was testing it by adding the attack to the character from the beginning which initialized the function and thus resolving the issue.

So I think I figured it out, it looks like you only get the 1 eCoin on any Diamonds that comes from mining and not the ones from cards

I am seeing the Diamonds not giving eCoin on hit too, anything we can do to help?

I am not seeing the issue of not getting coins on diamond hit even on fresh install. So I do not know how I can fix it.

Diamond currently does not actually give coins on hit

Sounds like fun
