Damage "Block"

[pOke]

Hello, I'm trying to make a damage "block" ability that upon activation it will "prevent" damage to the unit, by prevent I mean give it back the hp it would lose from damage. It technically WORKS as of now (except when the caster is full hp (but I'm not worried about that), but for some reason the caster still seems to take ~ about 2 damage or so but I'm not sure why. Thanks!

You want to completely null damage received? If yes, you could just use a conjunction of spell book and modified Hardened skin. That way when unit casts this ability you would only add that spell book, disable it and after X seconds (once the spell ends) enable it and remove it

 

[pOke]

Well I want spell damage to be blocked also.. hardened skin can't do that as far as I can tell.

Set Protection_CasterHP = (Life of Protection_Caster)
Should be placed as the first action in your second trigger???

 

[Nichilus]

Is this a toggleable ablity? If not, does this spell require target? or no target? (i.e. it activates on the caster after use)

 

[pOke]

Right now its based off of Frost Armor so I can easily have a buff and a special effect, but I might change it to a instant cast.

 

[Nichilus]

But it's the ability can be used only on the caster, he can't cast it on other unit, is that correct? Basically a Divine shield spell, but the caster can be attacked (he will null all damage)

Edit:
Anyway, looking at your triggers, there are a few problems:
1) it's not mui, so if more than 1 units cast this at a time, it will bug
2) you don't have any condition for 2nd trigger. So if 2 different units cast this ability, 2 different units will fire 2nd trigger, thus the currect caster will be healed even when previous caster takes damage
3) There is no need to do this: Unit - Set life of Protection_Caster to (Protection_CasterHP + ((Damage taken)); when you are supposed to null all damage. Leave out the (damage taken) part and just set the life to Protection_CasterHp.

In praxis, what happens now is you store life amount upon spell cast
So for example Start_HP = 100
Then caster takes 30 damage.
His hp is now 70, but you set his health as 100 (Start_Hp) +30 (Damage Taken) => 130. This results in the unit healing from receiving damage, instead of just nulling it.

Use a spellbook with Hardened Skin and Spell Damage Reduction then?

 

[Nichilus]

No, not spell reduction as it reduces incoming spell damage (up to magic-immune, which makes the unti unable to be targeted by spells).

I was thinking more along the lines of having dummy ability that starts this spell, then dummy unit that casts a modified version of "Anti-magic Shell (Magic Resistance)" (this version is not used in melee maps and it absorbs magic damage, up to a certain amount, which can be changed in object editor) and adding spell book with Hardened Skin.

Then using the trigger in hidden tags

Use this system: http://www.hiveworkshop.com/forums/spells-569/physical-damage-detection-gui-v1-0-0-1-a-231846/

With this trigger, no unit will take any damage.

OnDamage Events Game - damageEventTrigger becomes Equal to 1.00 Conditions Actions Set amount = 0.00

You just modify it to suit your needs.

Unit - Set life of Protection_Caster to (Protection_CasterHP + ((Damage taken))

The HP fluctuation is due to you adding the damage to a constant. Hitting it with a powerful nuke ability like Death Bolt will heal the unit considerably but then a simple 1 damage attack will lower its health to that amount.

You are after using the unit's current health added to the damage taken, not a constant of the unit's current health when the ability was cast.

 

[Maker]

Additionally, the "unit takes damage" runs before the actual damage is dealth. If you are at max health, and the event triggers, you try to add the damage taken to health. You can't go over max health like that, the health will stay at max value. Only after that is the actual damage applied.

Thanks! You've all been such a big help!

Use Berserk and set it's Damage Taken field to -1.00.
