I tested rampage with mutilator vs another 40 phys power item on in practice and I’m not seeing and damage values from Mutilors ability hit proc.
Every ability hit should hit for 2.5% of max hp according to item
Specifically the ground slam, Rumble, shows the same damage value ignoring the ability hit proc
Both items just hit a flat number. I’d understand if this was a dot but it’s clearly an ability hit. I can see the values on the rock and the leap, just not slam
