oww, nice. But how do I edit to be just fire and last for 5 seconds?

change this line for the amount of seconds, in the protection spell
protect:setParameter(CONDITION_PARAM_TICKS, 10 * 1000)
for the other, use this.
Lua: 
function onHealthChange(creature, attacker, primaryDamage, primaryType, secondaryDamage, secondaryType, origin)
    if creature and creature:isPlayer() then
        if creature:getCondition(CONDITION_ATTRIBUTES, CONDITIONID_COMBAT, 56) then
            if primaryType == COMBAT_FIREDAMAGE then
                primaryDamage = primaryDamage / 2
            end
            if secondaryType == COMBAT_FIREDAMAGE then
                secondaryDamage = secondaryDamage / 2
            end
        end
    end
    return primaryDamage, primaryType, secondaryDamage, secondaryType
end

No erros on TFS, but it doesn't work. It shows the effect but I still get normal damage. I put "primaryDamage / 100" and "secondaryDamage / 100" just to see if I would get lower damage, but it's just normal damage. Any ideas to what might be going wrong?

Try it with prints.

(and make sure you've registered the script in creaturescripts.xml as well as login.lua)
Lua: 
function onHealthChange(creature, attacker, primaryDamage, primaryType, secondaryDamage, secondaryType, origin)
	print("--------")
	print("script start")
    if creature and creature:isPlayer() then
		print("is player")
        if creature:getCondition(CONDITION_ATTRIBUTES, CONDITIONID_COMBAT, 56) then
			print("condition found")
            if primaryType == COMBAT_FIREDAMAGE then
				print("Primary damage type is FIRE.. reducing damage")
				print("Initial damage value: " .. primaryDamage)
                primaryDamage = primaryDamage / 2
				print("Modified damage value: " .. primaryDamage)
            end
            if secondaryType == COMBAT_FIREDAMAGE then
				print("Secondary damage type is FIRE.. reducing damage")
				print("Initial damage value: " .. secondaryDamage)
                secondaryDamage = secondaryDamage / 2
				print("Modified damage value: " .. secondaryDamage)
            end
        end
    end
    return primaryDamage, primaryType, secondaryDamage, secondaryType
end

When you are using the spell, are you getting the buff?

-- edit
I'm asking because I tested the script myself and it's working.
So I'm wondering if the spell is not applying to you properly.

Assuming it's not working, can you post your spell.xml line for your spell?

Thanks so much

How do I make the caster be immobilized while the effect is active?
