I have no idea what you are talking about.
I know how to make it since I have my own, but what you are saying doesn't make any sense to me.
i don't see how what he said is confusing. instead of having playertypes like 100 health, 150 health, he wants it so that you can adjust the "max health" of someone using events. you would assign a maxhealth variable to the client and make it so it can be adjusted with events (it also has to save). he needs the damage function to be packaged so it works with the health system he has.
since you can't actually edit the datablock for the individual player, you can make it so it pretends that 100 health is 150 health and just fractions the damage dealt. or you could make it so it has another "health" variable that decreases instead, and when it reaches 0, you die.
i don't see how what he said is complicated at all.
