Hi guys,

in my map I want that heros (like Marines, Goons, but Warbringer (Hero Reaver) too) can buy an item which activates a special attack.

This special attack should add some extra splash damage which doesn't hurt themselves (hurt allies would be ok).
In addition it should look and feel the coolest way possible.

OK, I've come to the conclusion that Scarabs would do that best. (Any other ideas?)
Lurkers are no option, since they are used elsewhere.

But now I need your help how to make the Scarabs attack. I already teleported them to the hero and ordered them to patrol to the enemy castle. But they pass all enemy units and try to move to the castle and explode before they can reach it.
I want them to attack the closest enemy unit or building.
How do I do that?

When using Scarabs I got another problem: Scarab damage is fixed to 6 + 4 per upgrade. Only the player controlling Warbringer Hero has an upgrade building for Scarab damage. So I could set every players upgrade damage to 50 resulting in 206 damage. But that would completely imbalance the Warbringer hero because every Player can choose his hero.
I could solve that by giving them to player 9 with 50 upgrades but then Scarabs would damage the hero they emerge from.
Any way to order the Scarabs to move a bit away and attack enemies then? (I don't use hypertriggers)

Any help or idea is appreciated.

@ attack units
solution 1:
junkyard ai script at hero position
solution 2:
send all units on random suizide missions

(requirements: you need a computer player allied with the player and unallied with the enemy)
(side effects: you can be damaged by the scrabs)
(special effect with solution 2: the scarabs move to the nearest unit, stop and attack still their lifetime is up. But they attack with a fast splash attack, much faster than every unit else... even dmg=0 can cause big damage)

solution 3:
move a reaver next to the hero (does not look nice)

The patrol AI script doesn't work on human players and the order action doesn't work on scarabs at all, so I can't imagine how.

This side effect is what im trying to avoid

I have 6 human players and 2 computer players already used. The comp players would meet the requirement, but if I send all units on random suicide missions it would spoil the rest of the game.

Since scarabs are not mine it would hurt me. Can I give the scarabs the player?

Possible. But im looking for something better.

Not patrol AI but order-action. But nvm, doesn't work either

Have the scarabs owned by a player that is not human, then set the generic command target (AI script) on where you want them to move, then use the AI Patrol to Upper Left Corner.

This can damage the user.

Well, then I see no way of doing it, since you can't give the human AIs.

Whoah, whoah, whoah, whoah, whoah, whoah, whoah, you can make a scarab Junk Yard Dog? I tried it but the scarab got pwnt.

OK as I supposed every method has its drawbacks. What I want isnt possible that way.

Now I implemented the following:

I create infested at the hero, order them to move away a bit and then give them the patrol order.
They come back very rarely to hurt me. Most times they hit targets ahead of me. And if they DO come back then usually don't explode directly beneath me. And melee enemies are not a big problem for the hero anyway.

So it's allright. Thanks for your help.

Why not use a siege tank or something?

Did you read everything?
