Giving a unit splash damage

[Karzama]

Hi,

So for my map I have a few different towers players can pick from (it's not a TD though) and I'm making some researches to go with them. The problem here is that I have a Nerubian Tower (it's a custom) that I want to have a research that gives it splash damage, the research needs to have 5 levels for it to fit in with the rest of the researches.

I've set all of the things in the OE to make it so that it could splash but I've set the radius to 0, then the research increases this radius. However it does nothing. Any ideas?

Make OoF item ability. Uncheck Item ability to false and then

That wouldn't add the slow from the tower though, that'd just add spell damage which I don't want.

I want to make it so that the tower starts of as a single target tower and you do researches to give it splash like a Frost Wrym does (obviously not as big radius as that though).

Find which spell include in FW. And put it
And set attack type to Siege

You might have to use the brute force method to make two versions of the tower - one with splash and one without - and have your upgrade change the unit type of towers. This is how Blizzard made it with Troll Headhunters -> Troll Berserkers. I've attached an example map showing the basics of which fields to change using Berserker Upgrade as base.

Upgrade is way to go.

If it's a global research instead of individual towers upgrading then you should either make use of chaos or berserker upgrade to make new units or maybe you could use an orb of annihilation inside a disabled spellbook and have a dummy passive, trigger it so that when the passive gains levels so does the orb of annihilation.

with the orb of annihilation you'd probably have to do more triggering to get the slow.
