Casterart\Targetart skill create problem.

I have created a new hero skill based on the Scepter of Mastery`s command ability, taking control of that unit. Now i set the cast1 to 10, so it takes 10 seconds for the skill to work, and in that time i want the hero to show some model which is really noticable so he can be stunned, but it doesnt work. I use:

Casterart=Abilities\Spells\Orc\Berserker\Berserkertarget.mdl
Effectart=Abilities\Spells\Orc\Berserker\Berserkertarget.mdl
Targetart=Abilities\Spells\Orc\Berserker\Berserkertarget.mdl

and of course i have tried each individually. What`s the deal here? who knows?

ALSO:

If you look up Roar in nightelfabilityfunc, there is something under that called Broa or something, used to determine the model with the claw which spawns over the unit. I`ve created a new skill that casts roar, but i want it to show the MagicRunes01.mdl instead of the roar model. How do i do this without changin roar too?

For both your questions it's the same awsner:

To do any changes to effect/target/caster art, you need normally (not always) to change the B or X part right below the spell, like in roar, you have the main spell and then the Broa part, you will need to change the broa art part to the other art you wanna use.

But we can't (yet) create new spell gfx code parts (all that start with either B or X, like Broa or Xhbl).:(
