Dragons!

Hello. I wanna make a dragon unit on my map. I want the Dragon to attack as a flamethrower. In other words I want it to have a constant attack which also deals splash-damage, kinda like the Orc Flamethrower unit. (That can be found in the editor) Any tips on how to do this? Thanks.

One easy way is to give the unit faster attackspeed and lower the damage, Its just an easy way though and might not be what you want.

Giving it a Missile - Line weapon type might also help...

attach this: Objects\Spawnmodels\Other\FlameThrower\FlameThrowerSpawnObj.mdx
to the dragon's head when he attacks

Thanks for all your answears.
But I do have one more question that I forgot to mention.
I would like the Dragon to have an attack that reduces the targets
armor by 5.
I use the "Orb of corruption" skill for this, and the skill works fine. But it only reduces the armor for one unit, not for all units covered in the splash-damage.
Is it possible to make a splash-attack that reduces armor for all units attacked?

You could make an Orb of Lightning that casts the Acid Bomb skill set to the same AoE radius as your damage.

Thats sounds good. But how is the trigger for that?

No trigger. The Orb of Lightning ability actually just has a % chance to cast a unit-target spell on striking. Acid Bomb is such a spell. Set the % chance to 100%.

"The Orb of Lightning ability actually just has a % chance to cast a unit-target spell on striking. Acid Bomb is such a spell."

What more spells can be used in the same way?

Use QUOTE tags instead of " " next time ;]

Spells that can be used - you answered it yourself - unit-target spell, so slows, curses, cripple, coil etc.
