Adding Special Effects to units

I am trying to add fire to the top of a choas peons hammer/axe thingy with the special effects trigger, but i cant seem to to it. Was is the location used for it? (I.E. hand right/hand left/overhea etc.)
Thx for any help in advanced

I believe the attachment point would be weapon. Create a modified Sphere ability and remove everything involving missile art. Then set the art to the fire and the attachment point to weapon. Afterwards, remove the other attachment points and give the ability to the chaos peon. This way, every chaos peon will have the ability when it's created without using a trigger.

i think weapon only works for heroes.

for peon it must be
right,
hand

Have a look at this:

Attachment Point Names:
overhead (floats over the unit's head, but doesn't sway with
the head as it animates)
head (sways with the unit's animation)
chest
origin (usually at the base of a unit's feet)
hand
foot
weapon (for heroes)
sprite (for buildings)
medium (for buildings)
large (for buildings)

Attachment Point Modifiers:
left
right
mount (for mounted units)
rear (for quadrupeds)
first (for buildings)
second (for buildings)
third (for buildings)
fourth (for buildings)
fifth (for buildings)
sixth (for buildings)
rallypoint (for buildings)

weapon often works on all the unit modelss with weapons actually, even the troll berserker has two weapon attachments

Whats a sphere ability? How do you do it? Thx or the weapon thing, i'll try that.

Sphere is located under Human\Units. What it does is permantely attach a special effect to the designated part of whatever unit has it. FOllow my instructions and you should be able to set it up, if not, ask here and I'll try to help you more.

I tried to change it, and set the caster attachment to weapon, then set it as the defualt activity but it still doesnt work. Can you make + export the ability for me? Thx for anyother help
