Ground Warning

[RupTure_QS]

Is there an effect I can use to warn before a spell is cast. Like how some bosses have a warning effect on the ground to signify for the player to dodge before they are hit by the spell. I can't really find a good one in wc3. The spell is a shadowy straight moving projectile, but it moves fast, so that's why I was wondering.

You could try spawning a confirmation indicator on the targeted point of the spell to inform user on where the spell will hit:
UI\Feedback\Confirmation\Confirmation.mdl

Then, put this special effect on the point where the spell will hit as an addition if you like: Abilities\Spells\Undead\RegenerationAura\ObsidianRegenAura.mdl

Another work around might be making the target icon part of the spell sort of like the blood mage's flamestrike where you see the ground burning before it sets ablaze, don't know much about spell making though.
