increase Spell Damage With Item

[Karam]

guys i rly need help here, iam trying to create an item to increase spell damage by level of hero X hero intelligence /25 i tried to use Damage Engine but i cant detect hero casting an ability... because i want to increase spell damage for basic abilities only but not Ultimates , so i tried to use Set Ability Real Level Field But the problem here is i want to set the damage of the ability And hero level x intelligence /25 for example if ability damage is 100 at lvl 3 and the hero intelligence is 50 so its gonna be, 3level x 50intelligence /25=6 +100 dmg =106 dmg, i dont know how to trigger it to be like that without using arithmetic arithmetic making it 100+3x50/25= 206 not 106, also i idk how to set the dmg like default damage(100) when hero drop the item, do i need to use variables? if someone knows how to detect a ability being cast in Damage Engine this fix everything

1) Unfortunately you cannot filter "Spells", best bet would be to trigger the ultimate damage so you can filter it using damage engine.
Something I do quite regularly is to use a dummy unit that casts an ability for me that I can then filter out with it's ability.
From there you could use DamageEngine's variable "NextDamageType" to set it to a custom one. (Note this is not the Acid/Force/SlowPoison types but the 6 to -2 that are present in the config here:

So you could easily modify the dummie's damage to number 7 and use that to filter ultimate spell damage.

2)As for your arithmetic I can't see it in your triggers due to it cutting off, so I'd recommend plugging your math into your computers calculator (or your phones whatever's handy.) and using brackets to see where it's going wrong because it should be straight forward.

3)Lastly I'd opt for damagemodifer event but that's just me

Do you want the item to increase the damage of your spells (1 damage instance) or create additional damage on top of the base spell (2 damage instance)?

If the former, you need to change the Event to "modifier":

• Game - DamageModifierEvent becomes Equal to 1.00

And then, instead of causing the damage yourself, you "set" the damage (= modify the damage before it hits the enemy).

• Set VariableSet DamageEventAmount = ((Real((Level of Blizzard for DamageEventSource))) x ((Real((Intelligence of DamageEventSource (Include bonuses)))) / 35.00))

Edit: Oh, Devalut was faster. To my knowledge you can't filter for specific spells, but you can "mark" them.

When dealing damage via trigger, set for example this before it:

• Set VariableSet NextDamageType = DamageTypeSpell

Then, add a condition to your trigger:

• DamageEventType Not equal to DamageTypeSpell

I'd go with what Devalut said, each Hero only has 1 Ultimate (assumedly) so it wouldn't be too difficult to manage. Keep in mind, if a Dummy is dealing the damage then it'll also be considered the (Killing unit) if the target were to die. This could potentially cause issues. I personally would trigger the Ultimate abilities completely from scratch, then you can properly Filter the damage since it'd all be triggered. At that point you wouldn't even need a Damage Engine, you could just incorporate Spell Power into the math for the damage amount.

@Ugabunda
You can modify damage in DamageEvent, this change was introduced in more recent versions of Damage Engine.
