Was wondering where u could find certain effects

Effects such as: when u cast Roar (attack damage increase) where can u find the actual damage % that is beeing added

i wanted to make a spell like roar but then make everyone in the AOE become spell immume now i wanted to do this without triggers so i thought i could use roar as a kind of dummy spell to see how i can create something like this of my own

I'm pretty sure its not possible without triggers.

You need to use "Pick Every Unit In Group Actions" in the trigger editor.

ye thats the problem i'd like to do it without triggers
