I don't know if there's a console command for this, but i need to increase the damage of a random weapon ( like 300 physical damage ) to test some things and thoughts about the takedowns.
It would be easier to simply wait for the CS, you can easily change the damage values of weapons in it. I don't think you can change a weapon's damage via the ingame console, you can however add strong items.
I don't give a [censored] about god mode damnit. I'm just trying to figure it out how the takedowns triggers, and i'm sure at 100 % that a weapon with like 1000 damage will takedown absolutely everything in one click. And that's exactly what i'm trying to do.
