Ability Problem

[ShenLong Kazama]

I wanna make a custom ability which adds fire to the unit. I made the ability but ingame the fire doesn't show up at all, i wanna use the blue fire doodad. I used the immolation ability as base but as i wrote above the fire doesn't appear.

Use base ability like basher or some aura better, then set all values to 0, then set the effect if you use Brilliance Aura the set the effect to Art - Target and Art - Target Attachment Point to where you want the effect to be shown, like if you want to add fire to hand use hand left or hand right.

But i wanna have the unit be able to turn it on and off.

Then, yes you're right, use ability like immolation or mana shield, it doesn't matter, same attachment points.

I tried but the fire doesn't appear.

Here's the map i made:

Okay testing...
Edit:
go to buffs change Art - Target to file below (i attached it, same model of fire, just extracted it), remove Art - Target Attachment Point, set Art - Target Attachments to 0.

Thanks works now.
