[Solved] How to make a character take reduced damage from certain mobs?

[SolarMisae]

I'm pretty new to mod characters, and while I've figured out how to do (most) of what I wanted on my own through searching, I can't seem to find the code (if there is one)  to make a character take reduced damage from specific mobs. I'd want this character to take 25% less damage from shadow monsters. Thanks in advance. n_n

I'm not sure, but this mod :

Add a damage reduction to winona. You could maybe look at the code, see how it works, and add a check for monster with shadow tag.

The mod above actually done by "health.abosrb". You can see how it works in Health:DoDelta function. But it is difficult to do tag filtering as the cause parameter can be a string. So, I suggest the following code, and it is server-only.

--TODO: customize these constants
--prefab name of your character
local CHARACTER_PREFAB = "wickerbottom"
--reduce 95% of the original damage
local DAMAGE_RESISTENCE = 0.95

AddComponentPostInit("combat",function(inst)
    if not GLOBAL.TheWorld.ismastersim then
        return
    end
    local oldbonusdamagefn = inst.bonusdamagefn
    inst.bonusdamagefn = function(attacker, target, damage, weapon)
        local bonus = 0
        if oldbonusdamagefn then
            bonus = oldbonusdamagefn(attacker, target, damage, weapon) or 0
        end
        -- things above are just for compatibility
        -- notice that shadow chesspieces has no "shadow" or "shadowcreature" tag
        if target.prefab == CHARACTER_PREFAB and (attacker:HasTag("shadow") or attacker:HasTag("shadowchesspiece")) then
            bonus = bonus - (damage + bonus) * DAMAGE_RESISTENCE
        end
        return bonus
    end
end)

First, thanks for the response! Any help is welcome and looking at the code helps understand it more. However, I keep crashing before character select. Image of crash screen included. 

Forgive me if I've done something very obviously wrong, putting stuff in the wrong places etc, I'm entirely new mods for this game and don't understand the code well. I pasted your code into my character's .lua file, and the only change I made was to first line of the code by switching "wickerbottom" with "wythe." Is there more I have to modify in the code itself or a different place I am to put this code? Since I am new to this forgive me if I ask to have it explained to me like I am 5. ;;

Try putting this in your modmain. I'm not sure but i think it's a modmain code.

Also, if you encounter a problem about a code not working, better to show exactly where you put it.

I see, thanks! I will do so in the future. I'll try putting the code in modmain and see how it goes. n.n

Edit: Ahh success! It's working flawlessly now. Thanks again to both of you!
