[Solved] - Issue with entity sub-types

So I'm trying to have my status effect work properly and for that, I'm wanting an extra .5 damage take place any time any hostile mob hits you. I thought I figured it out but no additional damage occurs and I think it's due to the entity sub-type.

Here's what my procedure looks like.

In my mind, monster entity makes sense but I also tried mob entity. I just want any hostile entity to be affected by this.
