@w00tyd00dthanks Yes this is another workaround to be able to change the damage compatible to other mods. I think it better fits to what you are doing (only change damage when attacking mob x). But in my case I want a "permanent" damamge modifier, in case critter is near, that's why I think changing the damageCalc function like Zupalex did, fits better (of course both work). I already implemented Zupalex solution and also adopted it to change insulation and absorb values, works great.
