How Would I use BPAdjustOutputDamage function to make attack hit for less?

I have been working on a mod which is adding custom dino variants with extra attacks and effects. I’ve got the dino creation down and i can add new attack indexes and use attackstates to do different attacks. However, some of the projectile attacks i added hit way too hard which is undesirable. I see there is a check box to allow the attack index to use BPAdjustOutputDamage, but when i pull up the function in the eventgraph i am completely lost on what to do. I know i can use statuscomponent to lower melee damage but i dont want all attacks affected as base attacks hit fine, i just want to decrease the damage output of certain attacks. I would really appreciate some help here as i’ve been stuck for hours and cant seem to find any tutorials.
