No I knew you wouldn't like that, and if you wanna keep the knockback effect for the skill, DO NOT REMOVE KB or KBA
... Besides, in the skill it has a variable which you can set to false so that it doesn't knock back.
But about the trees, it won't destroy them because I knew it would mess with your dungeons and forest and whatnot, so I left that out.
If you ever wanna change that, go into the trigger called "MS loop"
Somewhere in that trigger (somewhere near the middle,) you should find a line that looks like this:
Set KBA_DestroyTrees = False
Simply set that to true, and the Concussion Shot skill will knock units back AND destroy trees.
Don't forget to mention Kingz and Paladon too!
