I do have knowledge. So do you. No matter what the code is, they’re using 3 values/formulas. You can’t do it any other way. Boss health is a value. Ward health is a value. Ward decay is a formula (which has values).
So we do know that tweaking this system is as simple as changing those 3 values.
Much like we know that making a Monument of Protection drop more/less means changing one single value (same for PoE). I don’t need to read the code to know that this is true.
Which only means that you need to increase ward values and increase decay rate so both are affected the same way.
