Give both ranged/melee splash damage of their basic attack damage

Give both ranged/melee splash damage of their basic attack damage. A spell that makes units attacks do 50% of their attack damage to splash to nearby enemies. Help.

You want it on a spell or is i enough to make it hardcoded on the unit-type itself?

Because then you can just add it to the unit-type.

But if you want the splash damage with an ability, I dont think that such an ability exist.
You will need a DDS and deal splash damage yourself.
(Be aware that not all DDS can do that without problems.)

EDIT:
Cleave could work.

Cleave won't work on ranged units. You'd have to trigger it with damage detection.

You DO NOT need a DDS for this, all you need is to add item attack fire bonus (I'm not sure if that's the name but you will find it under items, it's with an icon orb of fire).
Once you add that ability, you need to calculate and subtract those 50% from your unit's base damage (cause the ability adds those 50% splash damage to your base dmg too). Let's say your unit's base damage is 10, you make the ability to deal 5 splash damage and it also gives +5 dmg to your base dmg, so you subtract it.
If you want to make unit's attack damage to divide to nearby units on impact then all you need to do is make the unit's attack type to splash and adjust the AOE as you wish.

That doesnt work.
Reducing by 50% does not the opposite of adding 50%
You need to add the inverse of 50%. which results in a decrease of 33.333%
But even that would not work as primary attribute, damage items and abilities and much much more also change your damage with that damage bonus.

Either make unit-types deal splash damage or use a DDS.

Well yeah, I've messed that with my map where the units' base damage that have this ability never changes. I realised this later -_-.
But, you can still make damage divide on impact, else you really need a DDS. :/

Why not use "Orb of Annihilation"? It is what the Undead Destroyer uses. It is an arrow ability so should inherit base attack damage. It also has configurable "splash" values. If the icon is a problem stick it inside a disabled spellbook and leave it auto-cast.
