How to make an amulet that consumes durability when it halves the health deduction?

The first method works well, but the durability is not consumed when the health is deducted due to eating.

local function OnEquip(inst, owner)
    if inst.components.fueled then
        owner.AnimState:OverrideSymbol("swap_hat", "fhl_hsf", "swap_hat")
        owner.components.health.externalabsorbmodifiers:SetModifier(inst, 0.5)
        inst.consumefn = function(attacked, data)
            inst.components.fueled:DoDelta(-0.02 * inst.components.fueled.maxfuel)
        end
        inst:ListenForEvent("attacked", inst.consumefn, owner)
        inst.components.fueled:StartConsuming()
    end
end

So I modified it to get this, but it doesn't work as expected.

local function OnEquip(inst, owner)
    if inst.components.fueled then
        owner.AnimState:OverrideSymbol("swap_hat", "fhl_hsf", "swap_hat")
        owner.components.health.externalabsorbmodifiers:SetModifier(inst, 0.5)
        inst.consumefn = function(inst, data)
            local amulet
            local hasAmulet = false
            for k, v in pairs(inst.components.inventory.equipslots) do
                if v and v:HasTag("hsf_protection") then
                    hasAmulet = true
                    amulet = v.prefab
                    break
                end
            end
            if hasAmulet and data and data.oldpercent and data.newpercent then
                local health_loss = data.oldpercent - data.newpercent
                if health_loss > 0 then
                    local durability_loss = 0.02 * amulet.components.fueled.maxfuel
                    amulet.components.fueled:DoDelta(-durability_loss)
                end
            end
        end
        owner:ListenForEvent("healthdelta", inst.consumefn)
        inst:AddTag("hsf_protection")
        inst.components.fueled:StartConsuming()
    end
end

Ohh, I was completed muddled, it should work in this way.

local function OnEquip(inst, owner)
    if inst.components.fueled then
        owner.AnimState:OverrideSymbol("swap_hat", "fhl_hsf", "swap_hat")
        owner.components.health.externalabsorbmodifiers:SetModifier(inst, 0.5)
        inst.consumefn = function(owner, data)
            local hasAmulet = false
            for k, v in pairs(owner.components.inventory.equipslots) do
                if v and v:HasTag("hsf_protection") then
                    hasAmulet = true
                    break
                end
            end
            if hasAmulet and data and data.oldpercent and data.newpercent then
                local health_loss = data.oldpercent - data.newpercent
                if health_loss > 0 then
                    local durability_loss = 0.02 * inst.components.fueled.maxfuel
                    inst.components.fueled:DoDelta(-durability_loss)
                end
            end
        end
        owner:ListenForEvent("healthdelta", inst.consumefn)
        inst:AddTag("hsf_protection")
        inst.components.fueled:StartConsuming()
    end
end
